Jet measurements with ALICE: substructure, dead cone, charm jets
Abstract
A selection of recent jet measurements are presented from the ALICE experiment at the CERN LHC in proton-proton collisions at TeV, focusing on substructure results for inclusive and charmed jets. The groomed jet momentum fractions () of inclusive full jets are shown for various jet resolution parameters, and , the groomed splitting radius () as well as the number of soft drops () of inclusive and charmed charged-particle jets are compared. The first direct measurement of the dead cone in heavy-flavor jets is also presented. Furthermore, the parallel momentum fractions of charmed D mesons and baryons are shown. Besides serving as a reference for jet structure modification measurements in heavy-ion collisions, these results provide new insight to QCD parton shower properties and flavor-dependent fragmentation processes.
