Dynamical Origin and the Pole Structure of X(3872)

The dynamical mechanism of channel coupling with the decay channels is applied to the case of coupled charmonium-DD* states with J(PC) = 1(++). A pole analysis is done and the DD* production cross section is calculated in qualitative agreement with experiment. The sharp peak at the D0D0* threshold and flat background are shown to be due to Breit-Wigner resonance, shifted by channel coupling from the original position of 3954 MeV for the 2(3)P(1),Q (Q) over bar state. A similar analysis, applied to the n = 2, P-3(2), P-1(1), P-3(0), allows us to associate the first one with the observed Z(3930) J = 2 and explains the destiny of P-3(0).
