Description

The masses of the recently reported by LHCb two pentaquark charmonium states Pc∗(4380) and Pc∗ (4450), which are supposed to have the configuration (uudcc-), have been estimated in the framework of the quasiparticle model of diquarks considering [ud][uc]c-bar configuration. The masses are reproduced very well, which indicates that the description of a diquark as a quasiparticle is very useful for describing multiquark state and understanding the dynamics of it.
