A Simple Model of Pentaquarks

High Energy Physics - Phenomenology 2024-07-31 v2

Abstract

We describe pentaquarks as baryo-charmonia with a color octet ccˉc\bar{c} core bonded to a color octet three-quark system. Fermi statistics of the light quark cloud allows to describe two pentaquark triplets: a lower one, well supported by experiment, and a higher one with strangeness. For the time being, the lowest line of the strange triplet has been experimentally identified in a 3σ3\sigma peak. Data also suggest (at least) two different production mechanisms for pentaquarks. We show how this can be described in the proposed scheme.
