χc0(1P) decay into Σ¯ Σπ in search of an I=1, 1/2− baryon state around K¯N threshold

We present the theoretical study of the process χc0(1P)→Σ¯Σπ decay, by taking into account the πΣ and πΣ¯ final state interactions of the final meson-baryon pair based on the chiral unitary approach. We show that the process filters the isospin I=1 in the πΣ channel and offers a reaction to test the...
