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…

Global analysis of $μ \to e$ interactions in the SMEFT

Filippo Delzanno, Kaori Fuyuto, Sergi Gonzàlez-Solís +1

We study current experimental bounds on charged lepton flavor violating (CLFV) $μ$ - $e$ interactions in the model-independent framework of the Standard Model Effective Field Theory…

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…

Padé approximants to $B \to π ℓ ν_{ℓ}$ and $B_{s} \to K ℓ ν_{ℓ}$ and determination of $∣ V_{u b} ∣$

Sergi Gonzàlez-Solís, Pere Masjuan, Camilo Rojas

In light of the first observation of the semileptonic decay $B_{s}^{0} \to K^{-} μ^{+} ν_{μ}$ by the LHCb collaboration, we revisit the determination of the CKM parameter $∣ V_{u b} ∣$ fro…

Tau decays into two mesons: an overview

Sergi Gonzàlez-Solís

We review the state-of-the-art theoretical analyses of tau decays into a pair of mesons and a neutrino. The participant vector and scalar form factors, $f_{+} (s)$ and $f_{0} (s)$ , a…

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…

Study of $B \to π ℓ ν_{ℓ}$ and $B^{+} \to η^{(')} ℓ^{+} ν_{ℓ}$ decays and determination of $∣ V_{u b} ∣$

Sergi Gonzàlez-Solís, Pere Masjuan

We reassess the $B \to π ℓ ν_{ℓ}$ differential branching ratio distribution experimental data released by the BaBar and Belle Collaborations supplemented with all lattice calcula…

New spectrum of negative-parity doubly charmed baryons: Possibility of two quasistable states

Mao-Jun Yan, Xiao-Hai Liu, Sergi Gonzàlez-Solís +4

The discovery of $Ξ_{cc}^{++}$ by the LHCb Collaboration triggers predictions of more doubly charmed baryons. By taking into account both the $P$ -wave excitations between the two c…

Insisting on the role of experimental data: the pseudoscalar-pole piece to the $(g_{μ} - 2)$ and the $∣ V_{u b} ∣$ from $B \to π ℓ ν_{ℓ}$ differential branching ratio

Sergi Gonzàlez-Solís, Pere Masjuan, Pablo Sanchez-Puertas

We employ a mathematical framework based on rational approximants in order to calculate meson form factors. The method profits from unitary, is systematic and data based, and is ab…

Jet energy loss in the quark-gluon plasma by stream instabilities

Massimo Mannarelli, Cristina Manuel, Sergi Gonzalez-Solis +1

We study the evolution of the plasma instabilities induced by two jets of particles propagating in opposite directions and crossing a thermally equilibrated non-Abelian plasma. In…
