Description

Precise theoretical predictions for the Higgs boson production in gluon fusion and the Drell-Yan production of a pair of leptons at NNLO in pQCD play an important role in testing the Standard Model. The recent computation of the full threshold contribution to the inclusive production cross section of the Higgs boson at N$^3$LO by Anastasiou. et. al. contains valuable information about the soft gluons resulting from virtual and real emission partonic subprocesses. In this talk, we will discuss how this information along with the Sudakov resummation of QCD amplitudes, renormalization group invariance and the mass factorization theorem can be utilized to obtain the threshold N$^3$LO perturbative QCD corrections to the rapidity distributions of the Higgs boson in gluon fusion and dileptons in the Drell-Yan process. This enables us to compute the full delta contribution, which was missing in the literature, and hereby give predictions for these very important observables at threshold N$^3$LO at the LHC.
