Popis: By describing the X(3872) using the extended Friedrichs scheme, in which DD¯* is considered as the dominant component, we calculate the decay rates of the X(3872) to π0 and a P-wave charmonium χcJ state with J=0, 1, or 2, and the rate of its decay to J/ψπ+π− with the help of the Barnes-Swanson model, where π+π− are assumed to be produced via an intermediate ρ state. This calculation shows that the decay rate of X(3872) to χc1π0 is 1 order of magnitude smaller than its decay rate to J/ψπ+π− and the decay widths of X(3872)→χcJπ0 for J=0, 1, 2 are of the same order.
