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…
A Texture of Leptons for the Koide and Alikhanov relations
Alessandro Strumia
Koide and Alikhanov proposed intriguing empirical relations among charged-lepton masses and neutrino mass splittings, respectively. We present mass-matrix textures that realise the…
Particle production from bubble collisions
Anish Ghoshal, Pratyay Pal, Alessandro Strumia
Collisions of ultra-relativistic bubbles during cosmological phase transitions can produce particles much heavier than the transition scale. Previous analyses modelled this process…
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…
Cosmological collider signals of modular spontaneous CP breaking
Shuntaro Aoki, Alessandro Strumia
We consider a modular-invariant extension of the Standard Model. Assuming that the modulus is the inflaton, the CP-violating phases of the Yukawa couplings evolve during inflation.…
