| dc.description.abstract | We investigate the meson-baryon interaction in coupled channels with the quantum numbers of the pentaquarks Pbss and Pbsss. The interaction is derived from an extension of the local hidden gauge approach to the heavy quark sector, which has demonstrated accurate results compared to experiments involving b, b states, and pentaquarks Pc and Pcs. In our study, we identify several molecular states with small decay widths within the chosen set of coupled channels. The spin-parity (J P) of these states is as follows: J P = 1/2− for pseudoscalar-baryon ( 1/2+) coupled channels, J P = 3/2− for pseudoscalar-baryon ( 3/2+) coupled channels, J P = 1/2− and 3/2− for vector-baryon ( 1/2+) coupled channels, and J P = 1/2−, 3/2−, 5/2 − for vector-baryon ( 3/2+) coupled channels. We search for the poles of these states and evaluate their couplings to the different channels. | |
