Warm Inflation, Neutrinos and Dark matter: a minimal extension of the Standard Model
Miguel Levy, João G. Rosa, Luis B. Ventura
We show that warm inflation can be realized within a minimal extension of the Standard Model with three right-handed neutrinos, three complex scalars and a gauged lepton/B-L U(1) s…
Yet another lesson on the stability conditions in multi-Higgs potentials
Igor P. Ivanov, Francisco Vazão
We discuss a rather common but often unnoticed pitfall which arises when deriving the bounded-from-below (BFB) conditions in multi-Higgs models with softly broken global symmetries…
Crossed two Higgs-doublet models: reduction of Yukawa parameters in the low-scale limit of left-right symmetry and other avatars
Gustavo C. Branco, Dipankar Das, Miguel Levy +1
We present new variants of the Two Higgs-Doublet Model where all Yukawa couplings with physical Higgs bosons are controlled by the quark mixing matrices of both chiralities, as wel…
Nondecoupling in Multi-Higgs doublet models
Francisco Faro, Jorge C. Romao, Joao P. Silva
We consider models with any number of Higgs doublets and study the conditions for decoupling. We show that, under very general circumstances, all the quadratic coefficients of the…
Type-I Seesaw with eV-Scale Neutrinos
G. C. Branco, J. T. Penedo, Pedro M. F. Pereira +2
We consider seesaw type-I models including at least one (mostly-)sterile neutrino with mass at the eV scale. Three distinct situations are found, where the presence of light extra…
