Refined approaches in second leptogenesis for the baryon-lepton asymmetry discrepancy
YeolLin ChoeJo, Kazuki Enomoto, Yechan Kim +1
The temperature-dependent mass of the heavy neutrino can lead to the second leptogenesis occurring below the electroweak scale, potentially explaining the large discrepancy between…

Second leptogenesis: Unraveling the baryon-lepton asymmetry discrepancy
YeolLin ChoeJo, Kazuki Enomoto, Yechan Kim +1
We propose a novel scenario to explain the matter-antimatter asymmetry by twofold leptogenesis, wherein heavy Majorana neutrinos exhibit temperature-dependent masses and engage in…

Searching for new physics effects in future mass and determinations
Hooman Davoudiasl, Kazuki Enomoto, Hye-Sung Lee +2
We investigate the phenomenology of the dark boson, , which is associated with a new Abelian gauge symmetry and couples to the standard model particles via kinetic mixing…
