摘要The next-to-leading order QCD corrections to gamma production via S-wave color-octet states gamma[S-1(0)(8), S-3(1)(8)] at the Tevatron and LHC is calculated. The K factors of total cross section ( ratio of next-to-leading order to leading order) are 1.313 and 1.379 for gamma[S-1(0)(8)] and gamma[S-3(1)(8)] at the Tevatron, while at the LHC they are 1.044 and 1.182, respectively. By fitting the experimental data from the CDF and D0, the matrix elements for S-wave color-octet states are obtained. And new predictions for gamma(1S) production are presented. The prediction for the polarization of inclusive gamma contains large uncertainty rising from the polarization of gamma(1S) from feed-down of chi(b). The production of gamma(3S) at the hadron colliders is also studied to avoid the large uncertainty mentioned above. To further clarify the situation, new measurements on the production and polarization for direct gamma(1S) and gamma(3S) are expected.
