Forward--backward asymmetry in the $H \to Z γ \to f f γ$ decay

A. I. Hernández-Juárez, G. Tavares-Velasco, A. Fernández-Téllez +1

We study the forward--backward asymmetry in the three-body decay process $H \to Z γ \to f f γ$ , induced by complex form factors in the $H Z γ$ vertex. To estimate its magnitude,…

Non-diagonal contributions to $Z I^^{3} V^{*}$ vertex, polarizations and bounds on $Z t q$ couplings

A. I. HernÃ¡ndez-JuÃ¡rez, G. Tavares-Velasco, R. GaitÃ¡n

We study the flavor-changing neutral current contributions to the trilinear neutral gauge boson couplings $Z I^^{3} V^{*}$ ( $V = Z$ , $I^^{3}$ ) at the one-loop level. Only the $C P$ -conserving…

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

A. I. HernÃ¡ndez-JuÃ¡rez, R. GaitÃ¡n

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…

Light quark contributions to Higgs decays

A. I. HernÃ¡ndez-JuÃ¡rez, R. GaitÃ¡n, R. Martinez

The literature establishes that the light fermions contributions to the decays $H \to Z I^^{3}$ and $H \to I^^{3} I^^{3}$ are negligible since their coupling with the Higgs is proportional to $m_{f}$ …

$H \to Z I^^{3}$ decay and $C P$ violation

A. I. HernÃ¡ndez-JuÃ¡rez, R. GaitÃ¡n, R. Martinez

This study examines the impact of $C P$ -violation on the signal strength $I^¼^{Z I^^{3}}$ , which was reported as $2.2 \pm 0.7$ by the LHC. We obtain constraints on the real and absorptive…
