Symmetries and Mass Degeneracies in the Scalar Sector
Howard E. Haber, O. M. Ogreid, P. Osland +1
We explore some aspects of models with two and three SU(2) scalar doublets that lead to mass degeneracies among some of the physical scalars. In Higgs sectors with two scalar doubl…
Solving a Fine-Tuning Problem of the Standard Model through the Introduction of Vector-Like Quarks
F. J. Botella, G. C. Branco, M. Nebot +2
We emphasise that even in the extreme chiral limit where only the top and bottom quarks acquire mass, quark mixing is physically meaningful. This implies that the natural value of…
Neutrino Physics and Leptonic Weak Basis Invariants
M. N. Rebelo
In this talk we present a powerful tool applied to the study of Leptonic Physics. This tool is based on the construction of Weak Basis invariant relations associated to different p…
CP violation in extended Higgs sectors
O. M. Ogreid, P. Osland, M. N. Rebelo
We discuss how one can identify CP violation (and conservation) in multi-Higgs-doublet potentials. After a brief review of CP violation in the 2HDM, we refer to the fact that for N…
