Cosmological vacuum selection in dynamical symmetry breaking at zero vacuum energy
Mateusz Duch, Alessandro Strumia
Coleman-Weinberg models invoke classical scale invariance to forbid scalar masses, but then add a dimensionful constant to cancel the vacuum energy of the broken vacuum. This incon…

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…
