We derive conservative model independent limits on the dark-matter–nucleon scattering cross section for sub-GeV dark matter. The leading-order hadronic couplings are most severely constrained by the supernova cooling argument via processes such as nucleon bremsstrahlung and pion–DM conversion. We rule out both spin-independent and spin-dependent cross sections larger than roughly $10^{−50}$...
Many well-motivated UV theories contain bonsonic light degrees of freedom, which can exhibit various wave-like behaviors at low energy. This leads to many new ideas and novel observables in recent years to probe new physics in astrophysical and laboratory setups alike. In this talk, I will briefly review a few examples in leveraging the wave-like features to test axions and ultralight dark...
Embed in Grassmannians, we can obtain the analytical hypergeometric function representation of multi-loop Feynman integrals with masses. We can make the classification among those hypergeometric function solutions by geometric configurations, and generalize Gauss relations among the hypergeometric functions to complete analytic continuation of the solutions. This method can be applicable to...
