Event shape variables measured using multijet nal states in proton-proton collisions at √s = 13 TeV

Abstract

The study of global event shape variables can provide sensitive tests of predictions for multijet production in proton-proton collisions. This paper presents a study of several event shape variables calculated using jet four momenta in proton-proton collisions at a centre-of-mass energy of 13TeV and uses data recorded with the CMS detector at the LHC corresponding to an integrated luminosity of 2:2 fbð€€€1. After correcting for detector e ects, the resulting distributions are compared with several theoretical predictions. The agreement generally improves as the energy, represented by the average transverse momentum of the two leading jets, increases.
