Description
We revisit the non-relativistic effective field theory called XEFT that is specifically designed for the description of X(3872) which is one of the most interesting candidates for hadronic molecules. In the framework XEFT, X(3872) is described as a bound state of two D mesons. Two new interaction terms consistent with general power counting rules are introduced to study the interaction of these D mesons. We investigate the effects of these new terms by explicitly calculating the decay rate of X(3872) up to next to leading order.
