The next-to-leading order Higgs impact factor at physical top mass: the real corrections
A bstract We compute the real corrections to the impact factor for the production of a forward Higgs boson, retaining full top-mass dependence. We demonstrate that the rapidity divergence is the one predicted by the BFKL factorization and perform the explicit subtraction in the BFKL scheme. We show that the IR-structure of the impact factor is the expected one and that, in the infinite-top-mass approximation, the previously known result is recovered. We also verify that the impact factor vanishes when the transverse momenta of the t -channel Reggeon goes to zero, in agreement with its gauge-invariant definition, exploiting the m t → ∞ expansion up to the next-to-next-to-leading order.
