Abstract

The X(3872) with quantum numbers JPC=1++ is considered as a composite hadronic state comprised of the dominant molecular D0D*0 component and other hadronic pairs-D±D*, J/??, and J/??. Applying the compositeness condition we constrain the couplings of the X(3872) to its constituents. We calculate two- and three-body hadronic decays of the X(3872) to charmonium states ?cJ and pions using a phenomenological Lagrangian approach. Next using the estimated XJ/?? and XJ/?? couplings we calculate the widths of X(3872)?J/?+h transitions, where h=p+p-, p+p-p0, p0?, and ?. The obtained results for the decay pattern of the X(3872) in a molecular interpretation could be useful for running and planned experiments. © 2009 The American Physical Society.
