Successful computation of quarkonium production cross sections

Demonstrated ease of use without pre-coding requirements

Abstract

We present NLOAccess, an online platform acting as a virtual access to automated perturbative computations of physical observables related to collider physics within collinear factorisation. 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 for instance to quarkonium production and/or heavy-ion collisions at leading and next-to-leading order in $\alpha_s$ 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.
