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…

The $D_{s 1} (2460) \to D_{s} I ¨ ^{+} I ¨ ^{-}$ decay from a $D_{s 1}$ molecular perspective

L. Roca, J. M. Dias, E. Oset

We conduct a theoretical study of the $D_{s 1} (2460) \to D_{s} I ¨ ^{+} I ¨ ^{-}$ decay from the perspective that the $D_{s 1}$ is a molecular state, built mostly from the $D^{*} K$ and $D_s^*…

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…
