MCgrid: Automated production of NLO QCD interpolation grids — •Enrico Bothmann and Steffen Schumann — II. Physikalisches Institut, Georg-August-Universität Göttingen
Fixed-order interpolation grids for NLO QCD calculations (APPLgrid, fastNLO) enable the reweighting of histogrammed observables, i.e. fast reevaluations with modified input parameters. These parameters include parton density functions (PDF), the strong coupling constant αS and choices for the renormalisation and the factorisation scale. The grids are used for PDF- and αS-fits as well as error estimates. We present the recently introduced interface MCgrid, that allows for an automated grid production using general-purpose Monte Carlo event generators. In this talk, we review the current status of MCgrid and discuss its applications and future developments.
