Exploring the low $$\tan \beta $$ region of two Higgs doublet models at the LHC
Publisher: Springer Science and Business Media LLC

DOI: 10.1140/EPJC/S10052-021-09609-4
Abstract: Current interpretations of the LHC results on two Higgs doublet models (2HDM) underestimate the sensitivity due to neglecting higher order effects. In this work, we revisit the impact of these effects using the current cross-section times branching ratio limits of the $$A\\rightarrow hZ, H \\rightarrow VV$$ A → h Z , H → V V and $$H\\rightarrow hh$$ H → h h channels. With a degenerate heavy Higgs mass $$m_\\varPhi $$ m Φ , we find that the LHC searches gain sensitivity to the small $$\\tan \\beta $$ tan β region after including loop corrections, even close to $$\\cos (\\beta -\\alpha )=0$$ cos ( β - α ) = 0 which is not reachable at tree level for all types of 2HDM. For a benchmark point with $$m_\\varPhi =300$$ m Φ = 300 GeV, $$\\tan \\beta .8(1.2)$$ tan β 1.8 ( 1.2 ) can be probed for the Type-I(II) 2HDM model for $$\\cos (\\beta -\\alpha )=0$$ cos ( β - α ) = 0 . When the deviation from $$\\cos (\\beta -\\alpha )=0$$ cos ( β - α ) = 0 is larger, the region for which current searches have exclusion potential becomes larger.
Convergent Bayesian global fits of 4D composite Higgs models
Publisher: Springer Science and Business Media LLC
Date: 05-2021
Abstract: Models in which the Higgs boson is a composite pseudo-Nambu-Goldstone boson offer attractive solutions to the Higgs mass naturalness problem. We consider three such models based on the minimal SO (5) → SO (4) symmetry breaking pattern, and perform convergent global fits on the models under a Bayesian framework in order to find the regions of their parameter spaces that best fit a wide range of constraints, including recent Higgs measurements. We use a novel technique to analyse the fine-tuning of the models, quantifying the tuning as the Kullback-Leibler ergence from the prior to the posterior probability on the parameter space. Each model is found to be able to satisfy all constraints at the 3 σ level simultaneously. As a by-product of the fits, we analyse the collider phenomenology of our models in these viable regions. In two of the three models, we find that the gg → H → γγ cross section is less than ∼90% that predicted by the SM, which is already in slight tension with experiment and could potentially be ruled out in the future high-luminosity run of the LHC. In addition, the lightest fermions F arising from the new strong dynamics in these models are seen in general to lie above ∼1 . 1 TeV, with the F → tW + and F → $$ \\overline{b}{W}^{+} $$ b ¯ W + decays offering particularly promising channels for probing these models in future collider searches.

Synchronization of relativistic particles in the hyperbolic Kuramoto model
Publisher: AIP Publishing
Date: 05-2018
DOI: 10.1063/1.5021701
Abstract: We formulate a noncompact version of the Kuramoto model by replacing the invariance group SO(2) of the plane rotations by the noncompact group SO(1, 1). The N equations of the system are expressed in terms of hyperbolic angles αi and are similar to those of the Kuramoto model, except that the trigonometric functions are replaced by hyperbolic functions. Trajectories are generally unbounded, nevertheless synchronization occurs for any positive couplings κi, arbitrary positive multiplicative parameters λi and arbitrary exponents ωi. There are no critical values for the coupling constants. We measure the onset of synchronization by means of several order and disorder parameters. We show numerically and by means of exact solutions for N = 2 that solutions can develop singularities if the coupling constants are negative, or if the initial values are not suitably restricted. We describe a physical interpretation of the system as a cluster of interacting relativistic particles in 1 + 1 dimensions, subject to linear repulsive forces with space-time trajectories parametrized by the rapidity αi. The trajectories synchronize provided that the particle separations remain predominantly time-like, and the synchronized cluster can be viewed as a bound state of N relativistic particle constituents. We extend the defining equations of the system to higher dimensions by means of vector equations which are covariant with respect to SO(p, q).
Lattice Study of the Kink Soliton and the Zero-mode Problem for ø 4 in Two Dimensions
Publisher: CSIRO Publishing
Date: 1999
DOI: 10.1071/PH99058
Abstract: Using lattice field theory techniques, we perform an exploratory study of the quantisation of the simplest extended object, the Λ ø 41+1 kink soliton, and the associated zero-mode contribution to the kink soliton mass in regions in and beyond the semiclassical regime. The calculations are done in the non-trivial scaling region so that our lattice results can be meaningfully compared with the classical and semiclassical continuum results. We show how to extract the kink from this full quantum field theory treatment and show, as a function of parameter space, where the zero-mode contributions become significant.

Model-independent approach for incorporating interference effects in collider searches for new resonances
Publisher: Springer Science and Business Media LLC
Date: 12-2020
DOI: 10.1140/EPJC/S10052-020-08763-5
Abstract: The presence of large-mass resonances in the data collected at the Large Hadron Collider would provide direct evidence of physics beyond the Standard Model. A key challenge in current resonance searches at the LHC is the modelling of signal–background interference effects, which can severely distort the shape of the reconstructed invariant mass distribution relative to the case where there is no interference. Such effects are strongly dependent on the beyond the Standard Model theory that must be considered as unknown if one aims to minimise any theoretical bias on the search results. In this paper, we describe a procedure which employs a physically-motivated, model-independent template functional form that can be used to model interference effects, both for the characterisation of positive discoveries, and in the presentation of null results. We illustrate the approach with the ex le of a scalar resonance decaying into a pair of photons.

Higgs Quark Flavor Violation: Simplified Models and Status of General Two-Higgs-Doublet Model
Publisher: Springer Science and Business Media LLC
Date: 02-2020
Abstract: We study quark flavor violating interactions mediated by the Higgs boson h . We consider observables involving a third generation quark, of both the up and the down quark sectors, like h → bs and t → ch . Using an effective field theory approach we systematically list all the possible tree-level ultraviolet completions, which comprise models with vector-like quarks and/or extra scalars. We provide upper bounds on the flavor violating transitions allowed by current limits stemming from low energy processes, such as meson mixing and b → s γ. We find that scenarios with vector-like quarks always have very suppressed flavor-violating transitions, while a general Two-Higgs-Doublet Model may have a sizeable rate. To study the latter case in detail, we perform a full numerical simulation taking into account all relevant theoretical and phenomenological constraints. Our results show that BR( t → ch ) [BR( h → bs )] are still allowed at the sub-percent [percent] level, which are being [may be] explored at the LHC [future colliders]. Finally, we have found that the mild mass-splitting discrepancy with respect to the SM in the B s meson system can be accommodated in the Two-Higgs-Doublet Model. If confirmed, it yields the prediction BR( h → bs ) ≃ 10 −4 , if the new contribution to the mass-splitting is dominated by tree-level Higgs boson exchange.

Introduction to Quantum Field Theory
Publisher: Cambridge University Press
Date: 04-08-2022
Abstract: This textbook offers a detailed and uniquely self-contained presentation of quantum and gauge field theories. Writing from a modern perspective, the author begins with a discussion of advanced dynamics and special relativity before guiding students steadily through the fundamental principles of relativistic quantum mechanics and classical field theory. This foundation is then used to develop the full theoretical framework of quantum and gauge field theories. The introductory, opening half of the book allows it to be used for a variety of courses, from advanced undergraduate to graduate level, and students lacking a formal background in more elementary topics will benefit greatly from this approach. Williams provides full derivations wherever possible and adopts a pedagogical tone without sacrificing rigour. Worked ex les are included throughout the text and end-of-chapter problems help students to reinforce key concepts. A fully worked solutions manual is available online for instructors.

Gravitational waves and electroweak baryogenesis in a global study of the extended scalar singlet model
Publisher: Springer Science and Business Media LLC
Date: 02-2019
Abstract: We perform a global fit of the extended scalar singlet model with a fermionic dark matter (DM) candidate. Using the most up-to-date results from the Planck measured DM relic density, direct detection limits from the XENON1T (2018) experiment, electroweak precision observables and Higgs searches at colliders, we constrain the 7-dimensional model parameter space. We also find regions in the model parameter space where a successful electroweak baryogenesis (EWBG) can be viable. This allows us to compute the gravitational wave (GW) signals arising from the phase transition, and discuss the potential discovery prospects of the model at current and future GW experiments. Our global fit places a strong upper and lower limit on the second scalar mass, the fermion DM mass and the scalar-fermion DM coupling. In agreement with previous studies, we find that our model can simultaneously yield a strong first-order phase transition and saturate the observed DM abundance. More importantly, the GW spectra of viable points can often be within reach of future GW experiments such as LISA, DECIGO and BBO.

Strong first order electroweak phase transition in 2HDM confronting future Z & Higgs factories
Publisher: Springer Science and Business Media LLC
Date: 04-2021
Abstract: The electroweak phase transition can be made first order by extending the Standard Model (SM) Higgs sector with extra scalars. The same new physics can explain the matter-antimatter asymmetry of the universe by supplying an extra source of CP violation and sphaleron processes. In this paper we study the existence of strong first order electroweak phase transition (SFOEWPT) in the type-I and type-II two Higgs doublet models (2HDM). We focus on how the SFOEWPT requirements constraint the spectrum of non-SM Higgs. Through the parameter space scan, we find that SFOEWPT suggests an upper limit on the masses of heavy Higgs $$ {m}_{A/H/{H}^{\pm }} $$ m A / H / H ± , which is around 1 TeV. High temperature expansion and Higgs vacuum uplifting is used for an analytical understanding of our results. After taking into account the probe ability on SFOEWPT from theoretical constraints, Higgs and Z -pole precision measurements up to the one-loop level at future Higgs & Z factories, sizeable loop corrections require $$ {m}_{A/{H}^{\pm }}-{m}_H $$ m A / H ± − m H ∈ (100 , 250) GeV to meet SFOEWPT condition for Type-II 2HDM, and $$ \left|{m}_{A/{H}^{\pm }}-{m}_H\right| $$ m A / H ± − m H ∈ (100 , 350) GeV or $$ \left|{m}_A-{m}_{H/{H}^{\pm }}\right| $$ m A − m H / H ± ∈ (100 , 350) GeV for Type-I 2HDM.

Abstract: The electroweak phase transition can be made first order by extending the Standard Model (SM) Higgs sector with extra scalars. Here, we focus on the strong first-order electroweak phase transition (SFOEWPT) in the Type-II two Higgs doublet models (2HDMs).

High-temperature expansion and Higgs vacuum uplifting are used for analytical understanding of our results. We find that sizeable loop corrections require [Formula: see text] to meet the SFOEWPT condition in the Type-II 2HDM. We also study the possibility of probing SFOEWPT at the one-loop level from Higgs and [Formula: see text]-pole precision measurements at future Higgs and [Formula: see text] factories.

Characterization of SABRE crystal NaI-33 with direct underground counting
Publisher: Springer Science and Business Media LLC
Date: 04-2021
DOI: 10.1140/EPJC/S10052-021-09098-5
Abstract: Ultra-pure NaI(Tl) crystals are the key element for a model-independent verification of the long standing DAMA result and a powerful means to search for the annual modulation signature of dark matter interactions. The SABRE collaboration has been developing cutting-edge techniques for the reduction of intrinsic backgrounds over several years. In this paper we report the first characterization of a 3.4 kg crystal, named NaI-33, performed in an underground passive shielding setup at LNGS. NaI-33 has a record low $$^{39}$$ 39 K contamination of 4.3 ± 0.2 ppb as determined by mass spectrometry. We measured a light yield of 11.1 ± 0.2 photoelectrons/keV and an energy resolution of 13.2% (FWHM/E) at 59.5 keV. We evaluated the activities of $$^{226}$$ 226 Ra and $$^{228}$$ 228 Th inside the crystal to be $$5.9\\pm 0.6~\\upmu $$ 5.9 ± 0.6 μ Bq/kg and $$1.6\\pm 0.3~\\upmu $$ 1.6 ± 0.3 μ Bq/kg, respectively, which would indicate a contamination from $$^{238}$$ 238 U and $$^{232}$$ 232 Th at part-per-trillion level. We measured an activity of 0.51 ± 0.02 mBq/kg due to $$^{210}$$ 210 Pb out of equilibrium and a $$\\alpha $$ α quenching factor of 0.63 ± 0.01 at 5304 keV. We illustrate the analyses techniques developed to reject electronic noise in the lower part of the energy spectrum. A cut-based strategy and a multivariate approach indicated a rate, attributed to the intrinsic radioactivity of the crystal, of $$\\sim $$ ∼ 1 count/day/kg/keV in the [5–20] keV region.
The ScotoSinglet Model: a scalar singlet extension of the Scotogenic Model
Publisher: Springer Science and Business Media LLC
Date: 06-2021
Abstract: The Scotogenic Model is one of the most minimal models to account for both neutrino masses and dark matter (DM). In this model, neutrino masses are generated at the one-loop level, and in principle, both the lightest fermion singlet and the lightest neutral component of the scalar doublet can be viable DM candidates. However, the correct DM relic abundance can only be obtained in somewhat small regions of the parameter space, as there are strong constraints stemming from lepton flavour violation, neutrino masses, electroweak precision tests and direct detection. For the case of scalar DM, a sufficiently large lepton-number-violating coupling is required, whereas for fermionic DM, coannihilations are typically necessary. In this work, we study how the new scalar singlet modifies the phenomenology of the Scotogenic Model, particularly in the case of scalar DM. We find that the new singlet modifies both the phenomenology of neutrino masses and scalar DM, and opens up a large portion of the parameter space of the original model.

Exploring fine-tuning of the Next-to-Minimal Composite Higgs Model
Publisher: Springer Science and Business Media LLC
Date: 04-2019
Abstract: We perform a detailed study of the fine-tuning of the two-site, 4D, Next-to-Minimal Composite Higgs Model (NMCHM), based on the global symmetry breaking pattern SO(6) → SO(5). Using our previously-defined fine-tuning measure that correctly combines the effect of multiple sources of fine-tuning, we quantify the fine-tuning that is expected to result from future collider measurements of the Standard Model-like Higgs branching ratios, in addition to null searches for the new resonances in the model. We also perform a detailed comparison with the Minimal Composite Higgs Model, finding that there is in general little difference between the fine-tuning expected in the two scenarios, even after measurements at a high-luminosity, 1 TeV linear collider. Finally, we briefly consider the relationship between fine-tuning and the ability of the extra scalar in the NMCHM model to act as a dark matter candidate, finding that the realisation of a Z 2 symmetry that stabilises the scalar is amongst the most natural solutions in the parameter space, regardless of future collider measurements.
