Revisiting constraints on magnetogenesis from baryon asymmetry
Yuta Hamada, Kyohei Mukaida, Fumio Uchida
Magnetic fields in the universe potentially serve as a messenger of primordial physics. The observationally suggested intergalactic magnetic fields may be a relic of helical primor…

Symmetries of Hot SM, Magnetic Flux & Baryogenesis from Helicity Decay
Yuta Hamada, Kyohei Mukaida, Fumio Uchida
We revisit the electroweak crossover of the Standard Model (SM) in the early Universe, focusing on the interplay between generalized global symmetries, magnetic flux dynamics, and…

Low-Scale Inflationary Magnetogenesis without Baryon Isocurvature Problem
Kazuki Yanagihara, Fumio Uchida, Tomohiro Fujita +1
Primordial magnetogenesis is an intriguing possibility to explain the origin of intergalactic magnetic fields (IGMFs). However, the baryon isocurvature problem has recently been po…
