Title: Inclusive production of the X(3872)

Abstract

If the X(3872) is a loosely-bound D*{sup 0}D{sup 0}/D{sup 0}D*{sup 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{sup PC}=1{sup ++}, the most important term in the factorization formula should be the color-octet {sup 3}S{sub 1} term. This is also one of the two most important terms in the factorization formulas for {chi}{sub cJ}. Since the color-octet {sup 3}S{sub 1} term dominates {chi}{sub cJ} production for many processes, the ratio of the inclusive direct production rates for X and {chi}{sub cJ} should be roughly the same for these processes. The assumption that the ratio of the production rates for X and {chi}{sub cJ} is the same for all processes is used to estimate the inclusive production rate of X in B meson decays, Z{sup 0} decays, and in pp collisions.
