$Ω_{c}$ excited states: a molecular approach with heavy-quark spin symmetry

Laura Tolos, Rafael Pavao, Juan Nieves

The LHCb Collaboration has recently discovered five excited $Ω_{c}$ states with masses between 3 and 3.1 GeV, four of them corroborated by the Belle Collaboration. We analyse the dyn…

Description of the $Ξ_{c}$ and $Ξ_{b}$ states as molecular states

Q. X. Yu, R. Pavao, V. R. Debastiani +1

In this work we study several $Ξ_{c}$ and $Ξ_{b}$ states dynamically generated from the meson-baryon interaction in coupled channels, using an extension of the local hidden gauge appro…

$Ω_{c}$ excited states with heavy-quark spin symmetry

Laura Tolos, Rafael Pavao, Juan Nieves

We study the $C = 1$ , $S = - 2$ , $I = 0$ sector, where five excited $Ω_{c}$ states have been recently observed by the LHCb Collaboration. We start from a recently developed unitarized baryo…

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…

$τ^{-} \to ν_{τ} M_{1} M_{2}$ , with $M_{1}, M_{2}$ pseudoscalar or vector mesons

L. R. Dai, R. Pavao, S. Sakai +1

We perform a calculation of the $τ^{-} \to ν_{τ} M_{1} M_{2}$ , with $M_{1}, M_{2}$ either pseudoscalar or vector mesons using the basic weak interaction and angular momentum algebra to relate…

Anomalous enhancement of the isospin-violating $Λ (1405)$ production by a triangle singularity in $Λ_{c} \to π^{+} π^{0} π^{0} Σ^{0}$

L. R. Dai, R. Pavao, S. Sakai +1

The decay of $Λ_{c}^{+}$ into $π^{+} π^{0} Λ (1405)$ with the $Λ (1405)$ decay into $π^{0} Σ^{0}$ through a triangle diagram is studied. This process is initiated by $Λ_{c}^{+} \to π^{+} K ˉ^{*} N$ , t…

Production of $N^{} (1535)$ and $N^{} (1650)$ in $Λ_{c} \to K ˉ^{0} η p$ $(π N)$ decay

R. Pavao, S. Sakai, E. Oset

In order to study the properties of the $N^{*}$ (1535) and $N^{*}$ (1650) we calculate the mass distributions of $M B$ in the $Λ_{c} \to K ˉ^{0} M B$ decay, with $MB=πN(I=1/2),ηp…
