Dynamical study of the possible molecular state X(3872) with the s-channel one gluon exchange interaction

Abstract

The recently observed X(3872) resonance, which is difficult to assign a conventional cc̄ charmonium state in the quark model, may be interpreted as a molecular state. Such a molecular state is a hidden flavor four quark state because of its charmonium-like quantum numbers. The s-channel one gluon exchange is an interaction which only acts in the hidden flavor multi-quark system. In this paper, we will study the X(3872) and other similiar hidden flavor molecular states in a quark model by taking into account the s-channel one gluon exchange interaction.
