Description

Fast interpolation-grid frameworks facilitate an efficient and flexible evaluation of higher-order predictions for any choice of parton distribution functions (PDFs) or value of the strong coupling constant $\alpha_s$. They constitute an essential tool for the extraction of PDFs and Standard Model parameters as well as studies of the dependence on the renormalization and factorization scales. The APPLfast project provides a generic interface between the parton-level Monte Carlo generator NNLOJET and both the APPLgrid and the fastNLO libraries for the grid interpolation. The extension of this toolchain for hadron-hadron collider processes at next-to-next-to-leading order (NNLO) in perturbative QCD is presented with an application to jet production at the LHC.
