Vacuum Stability in two-Higgs doublet models (2009)
Sa, Nuno Barros E, Barroso, Augusto, Ferreira, Pedro, Santos, Rui
In this work we review the status of tree-level vacuum stability in general two-Higgs doublet models. We also discuss the problem of Normal minima in some classes of potentials. In some of these...
Effects of periodic matter in kaon regeneration (2001)
Akhmedov, Evgeny, Barroso, Augusto, Keränen, Petteri
We study the effects of periodic matter in kaon regeneration, motivated by the possibility of parametric resonance in neutrino oscillations. The large imaginary parts of the forward kaon-nucleon...
