Abstract

In this manuscript we study the vector-vector interaction within the hidden-gauge formalism in a coupled channel unitary approach. In the sector C=1, S=1, J=2 we get a pole in the T matrix around 2572 MeV that we identify with the D_s2^*(2573), coupling strongly to the D^*K^*(D_s^*\ensuremathφ(\ensuremathω)) channels. In addition we obtain resonances in other exotic sectors which have not been studied before such as C=1, S=\ensuremath-1, C=2, S=0 and C=2, S=1. These ``flavor-exotic'' states are interpreted as D^*K^*, D^*D^*, and D_s^*D^* molecular states but have not been observed yet. In total we obtain nine states with different spin, isospin, charm, and strangeness of non-C=0, S=0 and C=1, S=0 character, which have been reported before.
