Properties of jet fragmentation using charged particles measured with the ATLAS detector in pp collisions at s =13 TeV

This paper presents a measurement of quantities related to the formation of jets from high-energy quarks and gluons (fragmentation). Jets with transverse momentum 100 GeV <pT<2.5 TeV and pseudorapidity |η|<2.1 from an integrated luminosity of 33 fb-1 of s=13 TeV proton-proton collisions are...
