We present an analysis of the lepton-flavor violating decay of the Higgs boson mediated by an ultralight gauge boson, $\chi$. Our analysis matches a model generating the lepton flavor-violating interaction $\bar{\ell}_i\ell_j\chi$ at tree level with

The effects of $CP$-violation on the reported result by the LHC $\mu^{Z\gamma}=2.2\pm 0.7$ for the $H\rightarrow Z\gamma$ signal strength are studied in new physics models, where bounds on the real and absorptive parts of the $CP$-violating form fact

An analysis of the off-shell $H^\ast\rightarrow ZZ \rightarrow \overline{\ell}_1\ell_1\overline{\ell}_2\ell_2$ decay width is presented for both unpolarized and polarized $Z$ gauge bosons in the scenario with the most general $H^*ZZ$ vertex function,

We study a Standard Model extension that provides a bicomponent dark matter scenario as well as a mechanism for the generation of left-handed neutrino masses. We extend the Standard Model scalar sector by adding an inert $SU(2)_L$ doublet with hyperc

The non-diagonal contributions to the trilinear gauge bosons couplings $Z\gamma V^\ast$ ($V=Z$, $\gamma$) at the one-loop level are calculated using complex flavor-changing neutral currents mediated by the $Z$ boson. We find that it is not possible t

Aspects of top quark physics can be studied at a future Circular Electron-Positron Collider (CEPC). In particular, Flavor-Changing Neutral Current interactions (FCNC) of the top quark can be studied even with a center-of-mass energy from $\sqrt{s}\gt

We study the flavor-changing decay $h\to \tau \mu$ with $\tau=\tau^-+\tau^+$ and $\mu=\mu^-+\mu^+$ of a Higgs boson at future hadron colliders, namely: a) High Luminosity Large Hadron Collider, b) High Energy Large Hadron Collider and c) Future hadro

We study Dark Matter (DM) abundance in the framework of the extension of the Standard Model (SM) with an additional $U(1)_X$ gauge symmetry. One complex singlet is included to break the $U(1)_X$ gauge symmetry, meanwhile one of the doublets is consid

In this paper we study the Flavor-Changing mediated by Higgs boson within Two-Higgs Doublet Model-III context. We explore the parameter space and, considering recent results, find new limits for the model parameters. We also obtain the total Higgs de
