Identifying $Σ (1380)$ and $Σ (1430)$ in the $J / ψ \to Λ π Σ ˉ$ reaction

Wen-Tao Lyu, Eulogio Oset, De-Min Li +1

We study the $J / ψ \to Λ π Σ ˉ$ reaction by looking at the $π^{+} Λ$ mass distribution at low energies, in search of signals for the low lying $Σ^{+}$ states. Apart from a clear signal o…

Role of $Σ (1660)$ in the $K^{-} p \to π^{0} π^{0} Σ^{0}$ reaction

Xing-Yi Ji, Si-Wei Liu, Wen-Tao Lyu +3

The processes of $K^{-} p \to π^{0} π^{0} Σ^{0}$ and $K^{-} p \to π^{0} Λ (1405)$ are studied within the effective Lagrangian approach. In addition to the ``background" contribution from the $u$ …

Finding a clean process $B^{-} \to K^{-} D^{0} K^{0}$ to probe absolutely exotic four-quark states

Man-Yu Duan, Guan-Ying Wang, Yun Liang +3

Motivated by the observations of $T_{c s ˉ 0} (2900)^{0}$ and $T_{c s ˉ 0} (2900)^{++}$ , we propose to search for $\tcsbar^0$ in the cleaner process $B^{-} \to K^{-} D^{0} K^{0}$ . In the $…

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…

How to unravel the nature of the $Σ^{*} (1430) (1/ 2^{-})$ state from correlation functions

Hai-Peng Li, Chu-Wen Xiao, Wei-Hong Liang +3

We calculate the correlation functions for the $K ˉ^{0} p, π^{+} Σ^{0}, π^{0} Σ^{+}, π^{+} Λ$ , and $η Σ^{+}$ states, which in the chiral unitary approach predict an excited $Σ^{*} (1/ 2^{-})$ state…
