DOI: 10.1007/jhep07(2017)012
Abstract: A bstractWe investigate a new type of a two-Higgs-doublet model as a solution of the muon g − 2 anomaly. We impose a softly-broken Z4 symmetry to forbid tree level flavor changing neutral currents in… read more here.

Abstract: Abstract We investigate the new contributions to the parameters gL and gR of the $$ Zb\overline{b} $$ Zb b ¯ vertex in a multi-Higgs-doublet model (MHDM). We emphasize that those contributions generally worsen the fit… read more here.

DOI: 10.1007/jhep11(2021)079
Abstract: Abstract We construct a three-Higgs doublet model with a flavour non-universal U(1) × ℤ2 symmetry. That symmetry induces suppressed flavour-changing interactions mediated by neutral scalars. New scalars with masses below the TeV scale can still… read more here.

Abstract: A bstractWe apply the unitarity bounds and the bounded-from-below (BFB) bounds to the most general scalar potential of the two-Higgs-doublet model (2HDM). We do this in the Higgs basis, i.e. in the basis for the… read more here.

Abstract: In a two Higgs-doublet model with $D_4$ flavor symmetry, we establish a relation between $\tan\beta$ and the Cabibbo angle. Due to a small number of parameters, the quark Yukawa sector of the model is very… read more here.
