Search for the $Σ^{*}$ state in $Λ_{c}^{+} \to π^{+} π^{0} π^{-} Σ^{+}$ decay by triangle singularity

Ju-Jun Xie, Eulogio Oset

A $Σ^{*}$ resonance with spin-parity $J^{P} = 1/ 2^{-}$ and mass in the vicinity of the $K ˉ N$ threshold has been predicted in the unitary chiral approach and inferred from the analys…

Triangle singularity in $τ^{-} \to ν_{τ} π^{-} f_{0} (980)$ ( $a_{0} (980)$ ) decays

L. R. Dai, Q. X. Yu, E. Oset

We study the triangle mechanism for the decay $τ^{-} \to ν_{τ} π^{-} f_{0} (980)$ , with the $f_{0} (980)$ decaying into $π^{+} π^{-}$ . This process is initiated by $τ^{-} \to ν_{τ} K^{* 0} K^{-}$ followed…

Polarization amplitudes in $τ^{-} \to ν_{τ} V P$ decay beyond the standard model

L. R. Dai, E. Oset

We use a recent formalism of the weak hadronic reactions $τ^{-} \to ν_{τ} M_{1} M_{2}$ to study the helicity amplitudes in $τ^{-} \to ν_{τ} V P$ decay. This recent formalism maps the transitio…

Coupled channels dynamics in the generation of the $Ω (2012)$ resonance

R. Pavao, E. Oset

We look into the newly observed $Ω (2012)$ state from the molecular perspective in which the resonance is generated from the $K ˉ Ξ^{*}$ , $η Ω$ and $K ˉ Ξ$ channels. We find th…

Helicity amplitudes in $B \to D^{*} ν ˉ l$ decay

L. R. Dai, E. Oset

We use a recent formalism of the weak hadronic reactions that maps the transition matrix elements at the quark level into hadronic matrix elements, evaluated with an elaborate angu…

Semileptonic decays of $B^{()}$ , $D^{()}$ into $ν l$ and pseudoscalar or vector mesons

L. R. Dai, X. Zhang, E. Oset

We perform a study of the $B^{(*)}$ , $D^{(*)}$ semileptonic decays, using a different method than in conventional approaches, where the matrix elements of the weak operators are ev…
