Threshold Resummation of Drell-Yan type colorless processes at LHC

Abstract

We look at the threshold effects in neutral and charged Drell-Yan production, Higgs boson production with a massive vector boson, and Higgs production in bottom quark annihilation at the Large Hadron Collider (LHC), up to the third order in QCD. Using third-order soft-virtual (SV) results and the universal properties of threshold logarithms, we find the process-dependent coefficients and improve the accuracy by including large threshold logarithms up to next-to-next-to-next-to-leading logarithmic (N${}^3$LL) order and matched with the latest N${}^3$LO results. We also show numerical results for the invariant mass distributions and total production cross sections for these processes. Our findings show that the theoretical scale uncertainties, which are about $0.4\%$ at N${}^3$LO in fixed-order calculations, decrease to less than $0.1\%$ at N${}^3$LO+N${}^3$LL after SV threshold resummation in the high invariant mass region.
