  • Modified PYTHIA mPDFs better satisfy symmetry and sum rules

    What the study found A modified algorithm based on PYTHIA produces equal-scale multi-parton distribution functions that are symmetric and satisfy the relevant sum rules more closely than earlier PYTHIA-based results. Why the authors say this matters The authors state that multi-parton distribution functions are important for predicting multiple scattering rates at hadron colliders, and the…

  • PineAPPL and MATRIX are linked for NNLO interpolation grids

    What the study found The study presents an interface between PineAPPL and Matrix that can calculate fully differential cross sections as interpolation grids with next-to-next-to-leading order (NNLO) accuracy in quantum chromodynamics (QCD, the theory of strong interactions) and next-to-leading order (NLO) accuracy in electroweak (EW) theory. Why the authors say this matters The authors say…
