Abstract: (APS)
The resummation calculation (resbos) is a widely used tool for the simulation of single vector boson production at colliders. In this work, we develop a significant improvement over the resbos code by increasing the accuracy from NNLL+NLO to N3LL+NNLO and release the resbos v2.0 code. Furthermore, we propose a new nonperturbative function that includes information about the rapidity of the system (IFY). The IFY functional form was fitted to data from fixed target experiments, the Tevatron, and the LHC. We find that the nonperturbative function has mild rapidity dependence based on the results of the fit.
