Weak corrections to Minimal Dark Matter annihilations
Dario Buttazzo, Mateusz Duch, Pier Paolo Giardino +1
We compute the one-loop weak corrections to the annihilation cross sections of fermionic Minimal Dark Matter multiplets. Infrared divergences cancel in the dominant -wave combin…

Baryogenesis from cosmological CP breaking
Mateusz Duch, Alessandro Strumia, Arsenii Titov
We show that baryogenesis can arise from the cosmological evolution of a scalar field that governs CP-violating parameters, such as the Yukawa couplings and the theta terms of the…

New physics in spin entanglement
Mateusz Duch, Alessandro Strumia, Arsenii Titov
We propose a theory that preserves spin-summed scattering and decay rates at tree level while affecting particle spins. This is achieved by breaking the Lorentz group in a non-loca…
