Title: The Y(3940), Z(3930) and the X(4160) as dynamically generated resonances from the vector-vector interaction

Abstract

We apply a unitary approach together with a set of hidden-gauge Lagrangians to study the vector-vector interaction. Concretely, we focus on the sector with quantum numbers charm C = 0 and strangeness S = 0 in the region around 4000 MeV. We get five poles, three of which could be identified with the Y(3940), Z(3930) and X(4160). These poles appear with quantum numbers I = 0 and J{sup PC} = 0{sup ++},2{sup ++} and 2{sup ++}, respectively, and can be considered as hadronic molecules made of D*D-bar*, D{sub s}*D-bar{sub s}*, decaying to a pair of light vectors, light-heavy vector or pseudoscalar-pseudoscalar.
