Searching for the LFV $γ γ e μ$ interaction at future $e^{-} e^{+}$ colliders

M. A. Arroyo-Ureña, R. Gaitán, Marcela Marín +2

We investigate the Lepton Flavor Violating (LFV) process $e^{+} e^{-} \to e^{+} e^{-} e μ$ ( $e = e^{-}, e^{+}, μ = μ^{-}, μ^{+}$ ) at future circular colliders, probing the effective $γ γ e μ$ inte…

Light quark contributions to Higgs decays

A. I. Hernández-Juárez, R. Gaitán, R. Martinez

The literature establishes that the light fermions contributions to the decays $H \to Z γ$ and $H \to γ γ$ are negligible since their coupling with the Higgs is proportional to $m_{f}$ . I…

$C P$ violation in the $H Z Z$ vertex and left-right asymmetries

A. I. Hernández-Juárez, R. Gaitán

We investigate new contributions to the $H Z Z$ vertex from the Flavor Changing Neutral Current (FCNC) involving the Higgs and $Z$ bosons. Our calculations reveal that the form facto…
