Abstract
Recently a new state of the system has been observed by the ATLAS Collaboration, with a mass of . This state has been identified with the -wave radial excitations of the system with parallel quark spins, called . The measured value of the mass corresponds to the average of the , 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.
