| 英文摘要 | We calculate the next-to-leading order (NLO) radiative correction to the color-octet h(c) inclusive production in e(+)e(-) annihilation at a super B factory, within the nonrelativistic QCD factorization framework. The analytic expression for the NLO short-distance coefficient (SDC) accompanying the coloroctet production operator O-8(hc) (S-1(0)) is obtained after summing both virtual and real corrections. The size of NLO correction for the color-octet production channel is found to be positive and substantial. The NLO prediction to the h(c) energy spectrum is plagued with unphysical end-point singularity. With the aid of the soft-collinear effective theory, those large end-point logarithms are resummed to the next-to-leading logarithmic (NLL) accuracy. Consequently, further supplemented with the nonperturbative shape function, we obtain the well-behaved predictions for the h(c) energy spectrum in the entire kinematic range, which awaits examination by the forthcoming Belle II experiment. |
