Production of interpolation grids for inclusive jet cross sections at ALICE — •Hector Pillot1,2, Rachid Guernane3, and Klaus Rabbertz2 — 1Grenoble Alpes University (UGA) — 2Karlsruhe Institut of Technology (KIT) — 3Laboratory of Subatomic Physics & Cosmology (LPSC)
The APPLfast project interfaces APPLgrid and fastNLO with the fixed-order cross section integrator NNLOJet. This produces interpolation grids that allow fast and accurate iterative computation of observables up to NNLO with different PDF sets or renormalization and factorization scales. This interface is employed in a workflow using the LAW and LUIGI packages for workflow management. As an example, differential cross sections of inclusive jet production from pp collisions at a center-of-mass energy of 5.02 TeV are computed within this workflow and are compared to experimental data from the ALICE collaboration. The cross sections are measured as a function of the jet pT and jet size parameter R. The cross sections are also compared using different PDF sets including PDF uncertainties and renormalization and factorization scale variations.
