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.

The fundamental particle theory called Quantum Chromodynamics (QCD) dictates everything about protons and neutrons, from their …

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.
