Novel Fermion Actions for Lattice Gauge Theory. The Standard Model of the universe is founded on quantum field theories in which gauge bosons mediate the forces between fermions, the constituents of matter. For example, the gluon of Quantum Chromodynamics (QCD) mediates the strong interactions between quarks as they compose protons, and neutrons. The only way to reveal the long-distance properties of this fundamental gauge theory from first principles is to numerically simulate the theory on a s ....Novel Fermion Actions for Lattice Gauge Theory. The Standard Model of the universe is founded on quantum field theories in which gauge bosons mediate the forces between fermions, the constituents of matter. For example, the gluon of Quantum Chromodynamics (QCD) mediates the strong interactions between quarks as they compose protons, and neutrons. The only way to reveal the long-distance properties of this fundamental gauge theory from first principles is to numerically simulate the theory on a space-time lattice. Simulating fermions on a lattice has proved very challenging. This project will explore novel and innovative improved fermion algorithms for the general problem of gauge theories on the lattice.Read moreRead less
Excitation spectra of quantum chromodynamics. Just as quantum electrodynamics describes the quantum mechanical excitation spectra of atomic systems, quantum chromodynamics (QCD) describes the excitation spectra of quark and gluon systems, such as the proton. This project will resolve the interactions underpinning the excitations of QCD, as being investigated at international facilities.
Interplay of the forces of nature: electroweak and strong interactions. The Large Hadron Collider in Switzerland will search for new physics by smashing protons together at the highest energies ever created in the laboratory. This project will focus on complementary searches for new physics by investigating novel phenomena associated with the mutual interactions of the strong and weak forces of nature.
Elucidating the role of quantum electrodynamics in hadron properties. This project will explore the fundamental mechanisms of nature making the neutron heavier than the proton; governing which nuclei are stable; and determining the current state of the Universe. Drawing on substantial supercomputing resources made available through international collaboration, this project will perform the first ab-initio simulation combining the quantum field theories governing elementary quarks, gluons, electr ....Elucidating the role of quantum electrodynamics in hadron properties. This project will explore the fundamental mechanisms of nature making the neutron heavier than the proton; governing which nuclei are stable; and determining the current state of the Universe. Drawing on substantial supercomputing resources made available through international collaboration, this project will perform the first ab-initio simulation combining the quantum field theories governing elementary quarks, gluons, electrons and photons; namely quantum chromodynamics and quantum electrodynamics. This project will develop novel theoretical and numerical techniques to confront the otherwise elusive electromagnetic contributions to hadronic properties and in doing so, address a wide range of important aspects of hadron structure and interactions.Read moreRead less
Structure of Hadronic Excitations from Lattice Quantum Chromodynamics. Quantum chromodynamics describes the fundamental strong interactions between quarks and gluons as they compose hadrons such as the proton or neutron. Beyond these lowest-energy systems, the quantum mechanical excitation spectra display a rich and complex structure. Remarkably, little is known about the internal structure of these states. The central goal of this project is to unveil the nature of hadrons and their excited sta ....Structure of Hadronic Excitations from Lattice Quantum Chromodynamics. Quantum chromodynamics describes the fundamental strong interactions between quarks and gluons as they compose hadrons such as the proton or neutron. Beyond these lowest-energy systems, the quantum mechanical excitation spectra display a rich and complex structure. Remarkably, little is known about the internal structure of these states. The central goal of this project is to unveil the nature of hadrons and their excited states using the first principles approach of lattice gauge theory. By elucidating aspects of hadron structure in terms of the most fundamental non-perturbative quark and gluon fields, the project will create new knowledge impacting on renowned experimental programs at international facilities.Read moreRead less
