Particle Physics

Fundamental symmetry tests of baryon number violation in low-energy experiments can probe beyond the standard model (BSM) explanations of the matter-antimatter asymmetry of the Universe. Neutron-antineutron oscillations are predicted to be a signature of many baryogenesis mechanisms involving low-scale baryon number violation. This publication presents first-principles calculations of neutron-antineutron matrix elements needed to accurately understand measurements of the neutron-antineutron oscillation rate.

Identify new dark matter candidates which are composite and made up of new elementary particles which could be discovered at the LHC

Identify directions in machine learning that are useful to theoretical particle physics.

For the first time we directly calculate a fundamental property of the neutron from the equations of quantum chromodynamics without relying on experimental measurements. We reach a sub-percent precision, many years ahead of what was previously conceived, thanks to a new algorithmical improvement to reduce the stochastic noise in our calculation.
