Description
We will discuss several key updates to the MSHT approximate N3LO PDFs; including the combination of these aN3LO QCD PDFs with QED effects, the first determination of the strong coupling constant at aN3LO, and further updates based on new theoretical information available at N3LO including more precise splitting functions for N3LO PDF evolution. All of this work has important consequences for phenomenology in a variety of physics analyses at the LHC currently being undertaken. We will review a selection of these, including consequences for Higgs production in gluon fusion, vector boson fusion Higgs production, Drell-Yan production and others.
