Assessment of the $a_{2} (1320)$ tensor-meson contribution to $η / η^{'} \to π^{0} γ γ$ decays

Rafel Escribano, Sergi Gonzàlez-Solís, Emilio Royo

In light of the recent measurement of the $η \to π^{0} γ γ$ decay by the KLOE-2 Collaboration, a previous analysis including vector- and scalar-meson exchange contributions using the V…

Sensitivity of the $η^{(')} \to π^{0} γ γ$ and $η^{'} \to η γ γ$ decays to a sub-GeV leptophobic $U (1)_{B}$ boson

Rafel Escribano, Sergi Gonzàlez-Solís, Emilio Royo

The sensitivity of the rare decays $η^{(')} \to π^{0} γ γ$ and $η^{'} \to η γ γ$ to signatures of a leptophobic $B$ boson in the MeV-GeV mass range is analyzed in this work. By a…

New-physics signatures via $C P$ violation in $η^{(')} \to π^{0} μ^{+} μ^{-}$ and $η^{'} \to η μ^{+} μ^{-}$ decays

Rafel Escribano, Emilio Royo, Pablo Sanchez-Puertas

In this work we investigate the prospect of observing new-physics signatures via $C P$ violation in $η^{(')} \to π^{0} μ^{+} μ^{-}$ and $η^{'} \to η μ^{+} μ^{-}$ decays at the REDTOP experi…

On Broad Kaluza-Klein Gluons

Rafel Escribano, Mikel Mendizabal, Mariano Quirós +1

In theories with a warped extra dimension, composite fermions, as e.g. the right-handed top quark, can be very strongly coupled to Kaluza-Klein (KK) fields. In particular, the KK g…

A theoretical analysis of the semileptonic decays $η^{(')} \to π^{0} l^{+} l^{-}$ and $η^{'} \to η l^{+} l^{-}$

Rafel Escribano, Emilio Royo

A complete theoretical analysis of the $C$ -conserving semileptonic decays $η^{(')} \to π^{0} l^{+} l^{-}$ and $η^{'} \to η l^{+} l^{-}$ ( $l = e$ or $μ$ ) is carried out within the framework of…

$π^{0}$ - $η$ - $η^{'}$ mixing from $V \to P γ$ and $P \to V γ$ decays

Rafel Escribano, Emilio Royo

An enhanced phenomenological model that includes isospin-symmetry breaking is presented in this letter. The model is then used in a number of statistical fits to the most recent ex…

A theoretical analysis of the doubly radiative decays $η^{(')} \to π^{0} γ γ$ and $η^{'} \to η γ γ$

Rafel Escribano, Sergi Gonzàlez-Solís, Renata Jora +1

The scalar and vector meson exchange contributions to the doubly radiative decays $η^{(')} \to π^{0} γ γ$ and $η^{'} \to η γ γ$ are analysed within the Linear Sigma Model and Vector…
