Pentaquark molecular states with hidden bottom and double strangeness

We investigate the meson-baryon interaction in coupled channels with the quantum numbers of the pentaquarks P₁ₒₒ and P₁ₒₒₒ. 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 ₁, ₁ states, and pentaquarks P₂ and P₂ₒ. In our study, we identify several molecular states with small decay widths within the chosen set of coupled channels. The spin-parity (JP) of these states is as follows: JP=1{2}^- for pseudoscalar-baryon (1{2}^+) coupled channels, JP=3{2}^- for pseudoscalar-baryon (3{2}^+) coupled channels, JP=1{2}^- and 3{2}^- for vector-baryon (1{2}^+) coupled channels, and JP=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.
