DESCRIPTION:Speakers: Álvaro Lozano Onrubia (IFT UAM-CSIC & Universidad A
 utónoma de Madrid)\nRadiative neutrino mass models represent a vast lands
 cape of possibilities for very exotic beyond Standard Model physics. In th
 is talk\, we will explore the idea of non-standard thermal histories in th
 e Zee-Babu neutrino mass generation model and specifically consider the po
 ssibility of hypercharge non-restoration in the early Universe. We will fi
 nd that careful treatment of finite-temperature perturbation theory is cru
 cial for mapping out the parameter space of phenomenological interest in s
 uch scenarios. The highlight of the talk will be a novel baryon asymmetry 
 generating mechanism which is driven by the high-temperature hypercharge-b
 reaking phase and the specific ingredients generically found in radiative 
 neutrino mass models.\n\nhttps://indico.ific.uv.es/event/7664/contribution
