Measurement of jet fragmentation in 5.02 TeV proton–lead and proton–proton collisions with the ATLAS detector

A measurement of the fragmentation functions of jets into charged particles in p+Pb collisions and pp collisions is presented. The analysis utilizes 28 nb −1 of p+Pb data and 26 pb −1 of pp data, both at s NN = 5.02 TeV, collected in 2013 and 2015, respectively, with the ATLAS detector at the LHC. T...
