ABSTRACT

The masses of the recently reported by LHCb two pentaquark charmonium states Pc* (4380) and Pc* (4450) which are suggested to possess pentaquark configuration () have been estimated considering a dihadronic state consisting of a meson  and a baryon (uud). The binding energies of the states have been estimated with a van der Walls type of molecular interaction between the hadrons. A spin interaction has also been considered. Masses of these two states are well reproduced with the aforesaid molecular interaction which indicates that the multiquarks Pc* (4380) and Pc* (4450) can be well described as meson-baryon bound states.
