摘要:We sum the leading logarithms alpha(n)(s) ln(2n-1) (1 - z), n = 1; 2, ... , near the kinematic threshold z = m(H)(2)/(s) over cap -> 1 at next-to-leading power in the expansion in (1 - z) for Higgs production in gluon fusion. We highlight the new contributions compared to Drell-Yan production in quark-antiquark annihilation and show that the final result can be obtained to all orders by the substitution of the colour factor C-F -> C-A, confirming previous fixed-order results. We also provide a numerical analysis of the next-to-leading power leading logarithms, which indicates that they are numerically relevant.
