$$P_c(4440)$$ P c ( 4440 ) and $$P_c(4457)$$ P c ( 4457 ) decay into $$\bar{D}\Sigma _c$$ D ¯ Σ c and $$\bar{D}\Lambda _c$$ D ¯ Λ c and the spin of the $$P_c$$ P c states
Abstract We address the issue of the width and spin assignment of the $$P_c(4440)$$ P c ( 4440 ) and $$P_c(4457)$$ P c ( 4457 ) pentaquark states. We calculate the partial decays widths of the particles into $$J/ \psi N$$ J / ψ N , $$\bar{D} \Sigma _c$$ D ¯ Σ c and $$\bar{D} \Lambda _c$$ D ¯ Λ c wit...
