We describe pentaquarks as ‘baryo-charmonia’ with a color octet c\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 3σ peak. Data also suggest two different production mechanisms for pentaquarks. We show how this can be described in the proposed scheme.

Abstract
We describe pentaquarks as ‘baryo-charmonia’ with a color octet c\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 3σ peak. Data also suggest two different production mechanisms for pentaquarks. We show how this can be described in the proposed scheme.| File | Dimensione | Formato | |
