Abstract

We present the resummed predictions for inclusive cross-section for Drell-Yan (DY) production as well as onshell Z,W±Z,W^\pm productions at next-to-next-to-next-to leading logarithmic (N3^{3}LL) accuracy. Using the standard techniques, we derive the NN-dependent coefficients in the Mellin-NN space as well as the NN-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 lnN\ln N exponentiation, we study the numerical impacts of exponentiating NN-independent part of the soft function and the complete gˉ0\bar{g}_0 that appears in the resummed predictions in NN 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 (N3^3LO). 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.
