Abstract:We present the calculation of the most important electroweak corrections to dijet production at the LHC and the Tevatron, comprising tree-level effects of O (α s α, α 2 ) and weak loop corrections of O (α 2 s α). Although negligible for integrated cross sections, these corrections can reach 10−20% in the TeV range for transverse jet momenta k T . Our detailed discussion of numerical results comprises distributions in the dijet invariant mass and in the transverse momenta of the leading and subleading jets. We find that the weak loop corrections amount to about −12% and −10% for leading jets with k T ∼ 3 TeV at the 14 TeV LHC and k T ∼ 800 GeV at the Tevatron, respectively. The electroweak tree-level contributions are of the same generic size and typically positive at the LHC and negative at the Tevatron at high energy scales. Generally the corrections to the dijet invariant mass distributions are smaller by at least a factor of two as compared to the corresponding reach in the k T distributions, because unlike the k T spectra the invariantmass distributions are not dominated by the Sudakov regime at high energy scales.

We consider higher-order QCD corrections to Higgs boson production through gluongluon fusion in the large top quark mass limit in hadron collisions. We extend the transverse-momentum (q T ) subtraction method to next-to-next-to-next-to-leading order (N 3 LO) and combine it with the NNLO Higgs-plus-jet calculation to numerically compute differential infrared-safe observables at N 3 LO for Higgs boson production in gluon fusion. To cancel the infrared divergences, we exploit the universal behaviour of the associated q T distributions in the small-q T region. We document all the necessary ingredients of the transverse-momentum subtraction method up to N 3 LO. The missing third-order collinear functions, which contribute only at q T = 0, are approximated using a prescription which uses the known result for the total Higgs boson cross section at this order. As a first application of the third-order q T subtraction method, we present the N 3 LO rapidity distribution of the Higgs boson at the LHC.
