Particle production from bubble collisions
Anish Ghoshal, Pratyay Pal, Alessandro Strumia
The paper investigates how ultra‑relativistic bubble collisions during cosmological phase transitions can generate very heavy particles, introducing a partonic‑like formalism based…
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.…
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…
Primordial magnetogenesis from a supercooled dynamical electroweak phase transition
Martin Arteaga Tupia, Anish Ghoshal, Alessandro Strumia
Observations of -ray from blazars suggest the presence of magnetic fields in the intergalactic medium, which may require a primordial origin. Intense enough primordial magnetic…
Solving the strong CP problem in string-inspired theories with modular invariance
Ferruccio Feruglio, Antonio Marrone, Alessandro Strumia +1
We show that solutions to the strong CP problem based on modular invariance can be extended to incorporate features that appear in string compactifications: quarks with mostly posi…
