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…
Unitarizing non-relativistic scattering
Marcos M. Flores, Kalliopi Petraki
Unitarity imposes coupled constraints on elastic and inelastic amplitudes. Satisfying them requires resummation of the self-energy contributions from both elastic and inelastic cha…
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…
The role of unitarisation on dark-matter freeze-out via metastable bound states
Kalliopi Petraki, Anna Socha, Christiana Vasilaki
In many Abelian and non-Abelian theories, standard calculations of radiative bound-state formation violate partial-wave unitarity - even at arbitrarily small couplings - when captu…
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…
Radiation back-reaction during dark-matter freeze-out via metastable bound states
Christiana Vasilaki, Kalliopi Petraki
The formation and decay of metastable bound states can deplete significantly the density of multi-TeV thermal-relic dark matter. The effect depends on the interplay of bound-state…
