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…
