Stability of neutral minima against charge breaking in the Higgs triplet model
P. M. Ferreira, B. L. Gonçalves
We analyse the possibility of charge breaking minima developing in the Higgs triplet model, and under what conditions they are deeper than charge-preserving ones. Analytical expres…

Electroweak vacuum lifetime in two Higgs doublet models
V. Branchina, F. Contino, P. M. Ferreira
We study the stability of neutral electroweak vacua in two Higgs doublet models, and calculate the lifetime of these states when the parameters are such that they are false vacua.…

Geometric picture of generalized-CP and Higgs-family transformations in the two-Higgs-doublet model
P. M. Ferreira, Howard E. Haber, M. Maniatis +2
In the two-Higgs-doublet model (THDM), generalized-CP transformations (phi_i--> X_{ij} phi_j^* where X is unitary) and unitary Higgs-family transformations (phi_i--> U_{ij} phi_j)…
