Abstract
Recently a new state of the b - anti b system has been observed by the ATLAS Collaboration, with a mass of 10530 +/- 5 +/- 9 MeV. This state has been identified with the n=3 P-wave radial excitations of the b - anti b system with parallel quark spins, called chi_b(3P). The measured value of the mass corresponds to the average of the J=0, 1 and 2 states, while the splittings of these states are not yet resolved. In this work we present predictions from different potentials models for the values of these splittings.
