$a_{0} (980)$ and $f_{0} (980)$ excitation in the $D^{+} \to π^{+} η η$ decay

Jing Song, Yi-Yao Li, Melahat Bayar +1

We have made a thorough study of the $D^{+} \to π^{+} η η$ reaction, recently measured by the BESIII collaboration, which shows an abnormal strength at high invariant masses in the $π η$ …

Revisiting the $Λ_{c}^{+} \to K ˉ^{0} η p$ reaction: the role of $N^{} (1535), N^{} (1650)$ and $Σ (1620)$

Jing Song, Melahat Bayar, Yi-Yao Li +1

We perform a theoretical study of the weak decay $Λ_{c}^{+} \to K ˉ^{0} η p$ using a coupled-channel chiral unitary approach that incorporates both pseudoscalar-baryon and vec…

Molecular states with bottom mesons and multistrange baryons systems

Jing Song, Yi-Yao Li, Eulogio Oset

We investigate molecular states formed by bottom mesons and multistrange baryons from both octet and decuplet flavor representations, using the local hidden gauge approach combined…

On the $π^{+} π^{-}$ and $D_{s}^{+} π^{\pm}$ mass spectra in the $D_{s 1} (2536) \to D_{s}^{+} π^{+} π^{-}$ decays

Jorgivan Morais Dias, Yi-Yao Li, Eulogio Oset

We have carried out an evaluation of the $π^{+} π^{-}$ and $D_{s}^{+} π^{+}$ mass distributions in the $D_{s 1} (2536)$ decay to $D_{s}^{+} π^{+} π^{-}$ , from the perspective that the $D_{s 1} (2536)$ i…

The $Λ_{c}^{+} \to Λ π^{+} π^{+} π^{-}$ reaction, and a triangle singularity producing the $Σ^{*} (1430)$ state

Yi-Yao Li, Jing Song, Eulogio Oset +2

We study the decay $Λ_{c}^{+} \to Λ π^{+} π^{+} π^{-}$ , focusing on the production of the $Σ^{*} (1430)$ resonance observed by the Belle Collaboration. Interpreted as a dynamically generated sta…
