Inclusive hch_c production at BB factories

Abstract

Within the nonrelativistic QCD (NRQCD) factorization framework, we investigate the inclusive production of the hch_c meson associated with either light hadrons or charmed hadrons at BB factory energy s=10.58\sqrt{s}=10.58 GeV. Both the leading color-singlet and color-octet channels are included. For the hch_c production associated with light hadrons, the total production rate is dominated by the color-octet channel, thus the future measurement of this process may impose useful constraint on the value of the color-octet matrix element ; for the hch_c production associated with charmed hadrons, the total production rate is about one order of magnitude smaller, and dominated by the color-singlet channel.Comment: v2, 23 pages, 1 table, 6 figures.
