| dc.description | If the X(3872) is a loosely-bound D^{*0} Dbar^0 / D^0 Dbar^{*0} molecule, its inclusive production rate can be described by the NRQCD factorization formalism that applies to inclusive quarkonium production. We argue that if the molecule has quantum numbers J^{PC} = 1^{++}, the most important term in the factorization formula should be the color-octet ^3S_1 term. This is also one of the two most important terms in the factorization formulas for chi_{cJ}. Since the color-octet ^3S_1 term dominates chi_{cJ} production for many processes, the ratio of the inclusive direct production rates for X and chi_{cJ} should be roughly the same for these processes. The assumption that the ratio of the production rates for X and chi_{cJ} is the same for all processes is used to estimate the inclusive production rate of X in B meson decays, Z^0 decays, and in p pbar collisions. | |
