摘要:
The possibility to study the fragmentation function of jets with energies below 50 GeV, which cannot be reconstructed in the heavy-ion environment, is explored. We propose to measure the imbalance distribution between prompt photon and charged hadrons with the ALICE experiment at LHC. In the present article, the case of proton-proton collisions at √s = 14 TeV is examined with Monte-Carlo simulations. Performances for prompt photon identification and rejection of the π 0 decay photons are presented. We find that the measurement in proton-proto...
