It provides the first full mass-dependent virtual NNLO QCD corrections and advances the treatment of double-real radiative corrections for W pair production.
Findings
Full mass-dependent virtual NNLO corrections computed.
Progress in handling double-real radiative corrections.
Enhanced theoretical precision for W pair production cross section.
Abstract
We discuss the result with full mass dependence for the virtual NNLO QCD corrections to the W boson pair production in the quark-anti-quark annihilation channel. We also report on our progress regarding the treatment of the double-real radiative corrections which, along with the virtual-real corrections, are the other two necessary ingredients for a theoretical prediction of the total cross section for W+ W- production to NNLO accuracy.
