Measurement of hadron composition in charged jets from pp collisions with the ALICE experiment

We report the first measurement of charged pion, kaon and (anti-)proton production in jets from hadron colliders. The measurement was carried out with the ALICE detector using 2×1082×108 minimum bias pp collisions at a centre-of-mass energy of s=7 TeV at the LHC. We present the π  , K and p transverse momentum (pTpT) spectra, as well as the spectra of the reduced momentum (zch≡pTtrack/pT,jetch), in charged jets of pTpT between 5–20 GeV/c. The measurement is compared to Monte Carlo calculations.
