The $Λ_{c}^{+} \to η π^{+} Λ$ reaction and the $Λ a_{0}^{+} (980)$ and $π^{+} Λ (1670)$ contributions

Man-Yu Duan, Wen-Tao Lyu, Chu-Wen Xiao +4

We study from the theoretical point of view the $Λ_{c}^{+} \to π^{+} η Λ$ reaction, recently measured by the Belle and BESIII Collaborations, where clear signals are observed for $a_0(980)…

Possible signal of an exotic $I = 1$ , $J = 2$ state in the $B \to D^{*-} D^{+} K^{+}$ reaction

Wen-Tao Lyu, Man-Yu Duan, Chu-Wen Xiao +2

We study the \proc reaction, showing that a peak in the \dk mass distribution around 2834 MeV reported by LHCb could be associated with a theoretical exotic state with that mass, a…

Theoretical study of the open-flavor tetraquark $T_{c s ˉ} (2900)$ in the process $B ˉ_{s}^{0} \to K^{0} D^{0} π^{0}$

Wen-Tao Lyu, Man-Yu Duan, Xiaoyu Wang +2

Recently, the LHCb Collaboration has measured two decay processes $B^{0} \to D ˉ^{0} D_{s}^{+} π^{-}$ and $B^{+} \to D^{-} D_{s}^{+} π^{+}$ related to isospin symmetry, where two new open-flavor tetraqua…

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…

Pentaquark molecular states with hidden bottom and double strangeness

Jing Song, Man-Yu Duan, Luis Roca +1

We investigate the meson-baryon interaction in coupled channels with the quantum numbers of the pentaquarks $P_{b ss}$ and $P_{b sss}$ . The interaction is derived from an extension o…

Searching for the two poles of the $Ξ (1820)$ in the $ψ (3686) \to Ξ ˉ^{+} K ˉ^{0} Σ^{*-} (π^{-} Λ)$ decay

Man-Yu Duan, Jing Song, Wei-Hong Liang +1

We propose the reaction $ψ (3686) \to Ξ ˉ^{+} K ˉ^{0} Σ^{*-}$ , with the $Σ^{*-}$ decaying to $π^{-} Λ$ in order to show evidence for the existence of two $Ξ (1820)$ states, one aroun…

Explore the properties of $Λ (1670)$ in the Cabibbo-favored process $Λ_{c}^{+} \to p K^{-} π^{+}$ decay

Sheng-Chao Zhang, Man-Yu Duan, Wen-Tao Lyu +3

Recently, the Belle and LHCb Collaborations have measured the $Λ_{c}^{+} \to p K^{-} π^{+}$ decay and reported the $p K^{-}$ invariant mass distribution, which shows a clear cusp structure a…
