Non-diagonal contributions to $Z γ V^{*}$ vertex, polarizations and bounds on $Z t q$ couplings

A. I. Hernández-Juárez, G. Tavares-Velasco, R. Gaitán

We study the flavor-changing neutral current contributions to the trilinear neutral gauge boson couplings $Z γ V^{*}$ ( $V = Z$ , $γ$ ) at the one-loop level. Only the $C P$ -conserving fo…

A Private SUSY 4HDM with FCNC in the Up-sector

M. A. Arroyo-Urena, J. Lorenzo Diaz-Cruz, Bryan O. Larios-Lopez +1

We present a SUSY model with four Higgs doublets of the ``private type", where each fermion type (up, down, and charged leptons) obtain their masses from a different Higgs doublet…

Rare top decay $t \to c γ$ with flavor changing neutral scalar interactions in two Higgs doublet model

Ricardo Gaitán, Estela A. Garcés, Roberto Martinez +1

Models beyond the Standard Model with extra scalars have been highly motivated by the recent discovery of a Higgs boson. The Two Higgs Doublet Model Type III considers the most gen…

Scalar-pseudoscalar interactions in neutrino-electron scattering

R. Gaitán, E. A. Garcés, O. G. Miranda +1

Many extensions to the Standard Model imply the existence of new charged scalar Higgs bosons. We study the contribution of a general scalar or pseudoscalar coupling for the neutrin…
