NLOAccess: automated online computations for heavy ions and quarkonia

Abstract

We present NLOAccess, an online platform acting as a virtual access to automated perturbative computations of physical observables related to hadronic physics, including heavy ions and quarkonium production. We discuss the design of the project and illustrate how, with few steps and without any need of pre-code or code compilation, a user can generate events and calculate cross sections related to quarkonium production and/or heavy ion collisions at leading and next-to-leading order in α s using MadGraph5 aMC-@NLO or HELAC-Onia. Finally, we report about the obtained results in terms of number of users and runs, and we illustrate the future plans of the project.Keywords Heavy ions • quarkonia • hadronic physics • event generators • online computation 1 A non exhaustive list of UFO models can be found at https://madgraph.mi.infn.it/models db.dat
