The dependence of inclusive one jet differential cross-section on the renormalization and factorization scale is studied. The choice when both scales μr, μfare set equal to jet transversal momentum is taken as a referential point and within a region around this choice, the inclusive one jet differential cross-section is calculated at next-to-leading order. Following the principle of minimal sensitivity (PMS), the region of local stability with respect to both scales is searched for. It is shown that it is well approximated by particular choice [Formula: see text] for total energies 7000 and 14,000 GeV.

Significant Effort

The ATLAS experiment relies heavily on simulated data, requiring the production of billions of simulated proton-proton collisions every run period. As such, the simulation of collisions (events) is the single biggest CPU resource consumer. ATLAS’s finite computing resources are at odds with the expected conditions during the High Luminosity LHC era, where the increase in proton-proton centre-of-mass energy and instantaneous luminosity will result in higher particle multiplicities and roughly five-fold additional interactions per bunch-crossing with respect to LHC Run-2. Therefore, significant effort within the collaboration is being focused on increasing the rate at which Monte Carlo events can be produced by designing and developing fast alternatives to the algorithms used in the standard Monte Carlo production chain.
