Abstract

Recently a new state of the bb̄ system has been observed by the ATLAS Collaboration, with a mass of 10530±5±9MeV. This state has been identified with the n=3 P-wave radial excitations of the bb̄ system with parallel quark spins, called χ _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.
