Comparison of public codes for Drell-Yan processes at NNLO accuracy

Parallel session talk QCD and Hadronic Physics T06: QCD and Hadronic Physics


Zoltan Trocsanyi (ELTE Eotvos Lorand University)


We present a detailed comparison of predictions computed by four publicly available computer codes for Drell-Yan processes at the LHC and Tevatron colliders. We point out that while there is agreement among the predictions at the next-to-leading order accuracy, the predictions at the next-to-next-to-leading order (NNLO) differ, whose extent depends on the observable. The sizes of the differences in general are at least similar, sometimes larger than the sizes of the NNLO corrections themselves. The talk will be based on arXiv: 2104.02400.
