Searching for the partner of the in the reaction
Jing Song, Zi-Ying Yang, Eulogio Oset
We study the reaction, recently analyzed by the LHCb collaboration, where a clear signal for the exotic state has been reported. We call the…

and decay into and and the spin of the states
Zi-Ying Yang, Jing Song, Wei-Hong Liang +1
We address the issue of the width and spin assignment of the and pentaquark states. We calculate the partial decays widths of the particles into , $\b…

Searching for signals of an exotic state of nature and the structure of the in the reaction
Jing Song, Zi-Ying Yang, Eulogio Oset
This paper investigates the decay process with the objective of finding a predicted molecular state with isospin , of nature, pl…
