NNLO VFNS dynamical parton distributions and weak-gauge and Higgs boson production — •Pedro Jimenez-Delgado — Institute for Theoretical Physics, University of Zurich, Switzerland
Since the required partonic subprocesses are only available in the approximation of massless initial-state partons, NNLO calculations are feasible at present only within the `variable flavor number scheme', in which also the heavy quark flavors (c,b,t) are treated as massless partons within the nucleon. Based on our recent NNLO dynamical parton distributions as obtained in the `fixed flavor number scheme', `variable flavor number scheme' distributions are generated and used to calculate the production rates for weak-gauge and Standard-Model Higgs boson at hadron colliders.
