Measurement of identified charged hadrons in charged jets from proton-lead collisions with ALICE at the LHC

The spectra of identified hadrons in jets offer possibilities to investigate the fragmentation of partons in detail. By comparing the results for proton-proton (pp) and proton-lead (p-Pb) we can test hypotheses about cold nuclear matter effects. The ALICE experiment at the LHC has excellent particle identification capabilities for tracks with transverse momentum ranging from 150 MeV/c to above 20 GeV/c. We report on the measurement of the charged hadron composition in charged jets from p-Pb collisions at √(s_NN) = 5.02 TeV. The jets are reconstructed from charged tracks using the anti-k_T algorithm. Charged hadrons are identified via their specific energy loss dE/dx in the ALICE TPC. We show the jet constituent spectra for different event multiplicities as functions of p^charged_T and z = p^{track, charged}_T/p^{jet, charged}_T and compare the results to those of pp collisions.
