This paper presents isolated photon-hadron correlations using pp and p-Pb data collected by the ALICE detector at the LHC. For photons with |η| < 0.67 and 12 < pT < 40 GeV/c, the associated yield of charged particles in the range |η| < 0.80 and 0.5 < pT < 10 GeV/c is presented. These momenta are much lower than previous measurements at the LHC. No significant difference between pp and p–Pb is observed, with PYTHIA 8.2 describing both data sets within uncertainties. This measurement constrains...This paper presents isolated photon-hadron correlations using pp and p-Pb data collected by the ALICE detector at the LHC.

This measurement constrains nuclear effects on the parton fragmentation in p–Pb collisions, and provides a benchmark for future studies of Pb-Pb collisions.» weiterlesen» einklappen
