Improved constraints on the mixing and mass of bosons from resonant diboson searches at the LHC at TeV and predictions for Run II
I. D. Bobovnikov, P. Osland, A. A. Pankov
New neutral vector bosons decaying to charged gauge boson pairs are predicted in many scenarios of new physics, including models with an extended gauge sector such as…
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…
Heavy Higgs boson decays in the alignment limit of the 2HDM
Bohdan Grzadkowski, Howard E. Haber, Odd Magne Ogreid +1
The Standard Model (SM)-like couplings of the observed Higgs boson impose strong constraints on the structure of any extended Higgs sector. We consider the theoretical properties a…
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…
