We present the C++ code BSMPT v2 which is an extension of previous for calculation strength electroweak phase transition in extended Higgs sectors. The new version includes features and extends already implemented models (the 2-Higgs-Doublet model (2HDM) its CP-conserving CP-violating versions Next-to-2HDM) by Complex Singlet Extension Standard Model (CxSM). major upgrade implementation computa...

Searches for a charged Higgs boson ($H^\pm$) decaying to charm quark and bottom ($H^\pm \to cb$) have been carried out at the Large Hadron Collider (LHC) in decay of top quarks ($t\to H^\pm b$). In recent search by ATLAS collaboration (with all Run II data, 139 fb$^{-1}$) local excess around $3\sigma$ has observed, which is best fitted with mass ($m_{H^\pm}$) 130 GeV product branching ratios (B...

Abstract The Dirac neutrino masses could be simply generated by a neutrinophilic scalar doublet with vacuum being dramatically different from the electroweak one. While case an eV-scale has been widely explored previously, we exploit in this work desert where is of scale. In regime, there would rare hope to probe keV-vacuum model via lepton-flavor-violating...

In the alignment limit of a multi-doublet Higgs sector, one of the Higgs mass eigenstates aligns with the direction of the scalar field vacuum expectation values, and its couplings approach those of the Standard Model (SM) Higgs boson. We consider CP-conserving Two-Higgs-Doublet Models (2HDMs) of Type I and Type II near the alignment limit in which the lighter of the two CP-even Higgs bosons, h...
