DsJ(2860) resonance and the sP=5 2- c s (c q) doublet
P. Colangelo, F. De Fazio, S. Nicotri
Abstract
We analyze the recently discovered DsJ(2860) meson using arguments based on the heavy quark expansion together with the experimental observations. We consider the possible quantum number assignments, arguing that the interpretation of the meson as the JP=3- c s state is favoured.
