$a_{0} (980)$ 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…

Final state interaction in the $Λ_{b} \to D^{+} D^{-} Λ, D^{0} D_{s}^{-} p, D_{s}^{+} D_{s}^{-} Λ$ reactions

Jing Song, Melahat Bayar, Eulogio Oset

We study the three-body decays $Λ_b \to D^+ D^- Λ,~D^0D_s^- p,~D_s^+D_s^-Λ$, considering both internal and external emission mechanisms that produce various meson-baryon final st…

Photoproduction of the $Λ (1800)$

Melahat. Bayar, Jing Song, L. R. Dai +1

We have carried out a study of the $γ p \to p K^{+} K^{*-} (K^{*-} \to K^{-} π^{0})$ , $γ p \to p K^{+} K^{*-} (K^{*-} \to K ˉ^{0} π^{-})$ a…

Precise determination of the $η Λ$ scattering length and effective range and relationship to the $Λ (1670)$ resonance

Man-Yu Duan, Melahat Bayar, Eulogio Oset

We use the Belle data on the $K^{-} p$ mass distribution of the $Λ_{c}^{+} \to p K^{-} π^{+}$ reaction near the $η Λ$ threshold to determine the $η Λ$ scattering length and effective range. We…

Two, three, many body systems involving mesons. Multimeson condensates

E. Oset, M. Bayar, A. Dote +8

In this talk we review results from studies with unconventional many hadron systems containing mesons: systems with two mesons and one baryon, three mesons, some novel systems with…
