Examining the sensitivity of FASER to Generalized Neutrino Interactions

Autor: Escrihuela, F. J., Flores, L. J., Miranda, O. G., Rendón, Javier, Sánchez-Vélez, R.

We investigate the sensitivity of the FASER$\nu$ detector, a novel experimental setup at the LHC, to probe and constrain generalized neutrino interactions (GNI). Employing a comprehensive theoretical framework, we model the effects of generalized neu

Rare decay $t\to c\gamma\gamma$ via scalar leptoquark doublets

Autor: Bolaños-Carrera, A., Sánchez-Vélez, R., Tavares-Velasco, G.

A calculation of the one-loop contribution to the rare three-body flavor changing neutral current top quark decay $t\to c\gamma\gamma$ is presented in the framework of models with one or more scalar leptoquark $SU(2)$ doublets with hypercharge $7/6$.

Neutrino electromagnetic properties in a Leptoquark model

Autor: Sánchez-Vélez, R.

The neutrino magnetic dipole moment is studied in a simple extension of the SM augmented with a scalar Leptoquark with quantum numbers $(\bar{\boldsymbol{3}},\boldsymbol{1},1/3)$. In order to reach a sizeable neutrino magnetic moment, we include in t

Flavor changing neutral current decays $t\to c X$ ($X=\gamma,\,g,\, Z,\, H$) and $t\to c\bar \ell\ell $ ($\ell=\mu,\,\tau$) via scalar leptoquarks

Autor: Bolaños, A., Sánchez-Vélez, R., Tavares-Velasco, G.

The flavor changing neutral current decays $t\to c X$ ($X=\gamma,\,g,\, Z,\, H$) and $t\to c\bar \ell\ell $ ($\ell=\mu,\,\tau$) are studied in a renormalizable scalar leptoquark (LQ) model with no proton decay, where a scalar $SU(2)$ doublet with hyp

Decay $\phi\to Z \gamma\gamma$ ($\phi=h, H,A$) in the minimal supersymmetric standard model

Autor: Sánchez-Vélez, R., Tavares-Velasco, G.

Publikováno v: Phys. Rev. D 99, 055024 (2019)

The decays of the CP-even ($h,\,H$) and the CP-odd ($A$) Higgs bosons $h,\,H,\,A\to Z\gamma\gamma$ are calculated in the context of the minimal supersymmetric standard model (MSSM), where they are induced at the one-loop level via box and reducible F

Decays $A \to Z\gamma\gamma$ and $\phi \to Z\gamma\gamma$ ($\phi=h,H$) in two-Higgs doublet models

Autor: Sánchez-Vélez, R., Tavares-Velasco, G.

Publikováno v: Phys. Rev. D 97, 095038 (2018)

The one-loop contributions to the decays of the $CP$-odd and $CP$-even scalar bosons $A\to Z\gamma\gamma$ and $\phi\to Z\gamma\gamma$ ($\phi=h,H$) are calculated within the framework of $CP$-conserving THDMs, where they are induced by box and reducib
