Measurement of Identified Charged Hadrons in Charged Jets from Proton-Lead Collisions with ALICE at the LHC — •Martin Schmidt for the ALICE collaboration — Physikalisches Institut, Universität Tübingen
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 √sNN= 5.02 TeV. The jets are reconstructed from charged tracks using the anti-kT 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 pTcharged and z=pTtrack, charged/pTjet, charged and compare the results to those of pp collisions.
