The universe contains far more matter than antimatter, yet the Standard Model of particle physics cannot explain why. Explaining this imbalance requires new physics beyond the Standard Model (BSM).

What they work on
- Calculate the electric dipole moments of protons and neutrons induced by theories beyond the Standard Model, to probe the source of the universe's matter-antimatter asymmetry.
- Use the gradient flow, which smooths quantum fields by adding a flow time scale, within lattice QCD simulations to compute the strong-force part of matrix elements from quark and theta-term CP violation.
- Extend the gradient-flow method to all CP-violating contributions to the electric dipole moments of nucleons and light nuclei, laying groundwork for interpreting future high-intensity experiments.
- Develop calculation tools that serve as alternatives to traditional methods and can be applied to other matrix element calculations, including those relevant to dark matter candidates.
More about the research
One promising clue is the electric dipole moment (EDM) of particles like the neutron and proton, a slight separation of positive and negative charge inside them. The same sources of new physics that could explain the matter-antimatter imbalance would also produce an EDM, so measuring and predicting EDMs can test these theories.
Why it matters
This is basic research. It would provide the theoretical link needed to interpret future measurements of proton, neutron and light-nucleus electric dipole moments. That link could help determine which theories beyond the Standard Model can explain why the universe contains more matter than antimatter. The methods could also inform calculations related to dark matter candidates.
