Revisiting the $Λ_{c}^{+} \to n π^{+} η$ decay in light of the BESIII measurement

Meng-Yuan Li, Jing Tang, Wen-Tao Lyu +2

Motivated by the latest BESIII measurements on $Λ_{c}^{+} \to n π^{+} η$ , we perform a systematic theoretical study of this decay. We take into account contributions from the $N (1535)$ stat…

Role of the $I^£ (1430) (1/ 2^{-})$ in the $J / I ¨ \to I^ I^ˉ I ¨ ^{0}$ reaction

Yu-Shan Ren, Wen-Tao Lyu, Eulogio Oset

We study the $J / I ¨ \to I^ˉ I^ I ¨ ^{0}$ reaction, an isospin violating reaction, by looking at the trios of baryon-antibaryon-pseudoscalar meson that conform a singlet of $\text{SU}(3…

Identifying $I^£ (1380)$ and $I^£ (1430)$ in the $J / I ¨ \to I^ I ¨ I^ˉ £$ reaction

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

We study the $J / I ¨ \to I^ I ¨ I^ˉ £$ reaction by looking at the $I ¨ ^{+} I^$ mass distribution at low energies, in search of signals for the low lying $I^£^{+}$ states. Apart from a clear s…

Role of $I^ (1690)$ in the $J / I ¨ \to I^^{0} I^ˉ K^{0}$ reaction

Wen-Tao Lyu, Lian-Rong Dai, Eulogio Oset

Motivated by the recent BESIII measurements of the $J / I ¨ \to I^^{0} I^ˉ K_{S}^{0} + c . c .$ process, we investigate this reaction by considering the contributions from the $I^ (1690)$ , $Î…

Unveiling the elusive $I^£ (1380)$ resonance through coupled-channel dynamics in $I^_{c}^{+} \to I^\cdot I ¨ ^{+} I^$ reaction

Wen-Tao Lyu, Si-Wei Liu, Jia-Jun Wu +2

We investigate the $I^_{c}^{+} \to I^\cdot I ¨ ^{+} I^$ decay measured by the Belle and BESIII Collaborations, focusing on the possible role of the $I^£ (1380)$ state with spin-parity $J^{P} = 1/ 2^{-}$ .…

Role of $a_{0} (1710)$ in the $J / I ¨ \to I ¨ ^{+} I ¨ ^{-} I ¨ $ and $J / I ¨ \to I^^{3} I ¨ ^{0} I ¨ $ reactions

Wen-Tao Lyu, Luis Roca, Eulogio Oset

We investigate the strong decay $J / I ¨ \to I ¨ ^{+} I ¨ ^{-} I ¨ $ and the radiative decay $J / I ¨ \to I^^{3} I ¨ ^{0} I ¨ $ , taking into account the $S$ -wave $K^{*} K ˉ^{*}$ , $I ¨ I ¨ $ and $I ¨ I ¨ $ final-state intera…
