Resummed Drell-Yan cross-section at N$^3$LL
Abstract
We present the resummed predictions for inclusive cross-section for Drell-Yan (DY) production as well as onshell productions at next-to-next-to-next-to leading logarithmic (NLL) accuracy. Using the standard techniques, we derive the -dependent coefficients in the Mellin- space as well as the -independent constants and match the resummed result through the minimal prescription matching procedure with that of existing next-to next-to leading order (NNLO). In addition to the standard exponentiation, we study the numerical impacts of exponentiating -independent part of the soft function and the complete that appears in the resummed predictions in space. All the analytical pieces needed in these different approaches are extracted from the soft-virtual part of the inclusive cross section known to next-to-next-to-next-to leading order (NLO). We perform a detailed analysis on the scale and parton distribution function (PDF) variations and present predictions for the 13 TeV LHC for the neutral Drell-Yan process as well as onshell charged and neutral vector boson productions.
