Unitarity violation and restoration in radiative bound-state formation
Marcos M. Flores, Kalliopi Petraki
State-of-the-art calculations motivated by dark matter exhibit severe violation of partial-wave unitarity in the non-relativistic regime in radiative bound-state-formation processe…

Critical and super-critical scatterings in baryogenesis and leptogenesis
Marcos M. Flores, Kalliopi Petraki, Anna Socha
In many theories, matter-antimatter asymmetries originate from out-of-equilibrium decays and scatterings of heavy particles. While decays remain efficient, scattering rates typical…

Unitarity in the non-relativistic regime and implications for dark matter
Marcos M. Flores, Kalliopi Petraki
Unitarity sets upper limits on partial-wave elastic and inelastic cross-sections, which are often violated by perturbative computations. We discuss the dynamics underlying these li…
