Universal Seesaw Leptogenesis
K. S. Babu, Maximilian Berbig, Srubabati Goswami +1
We study the implications for leptogenesis in a class of left-right symmetric model, where all fermion masses are induced through the Universal Seesaw mechanism. Unlike conventiona…

Type II Seesaw Leptogenesis in a Majoron background
Maximilian Berbig
We discuss spontaneous Leptogenesis in the Type II Seesaw model of neutrino masses featuring an electroweak triplet scalar in a coherent pseudo Nambu-Goldstone boson (pNGB) bac…

About electroweak domain walls in Majoron models
Maximilian Berbig
Some time ago it was claimed in "Spontaneous Breaking of Lepton Number and Cosmological Domain Wall Problem" (Phys. Rev. Lett. 122, 151301 (2019)) that non perturbative instantons…
