Inhaltszusammenfassung
The transverse momentum (pT) distribution of primary charged particles is measured in non-singlediffractive p–Pb collisions at √sNN = 5.02 TeV with the ALICE detector at the LHC. The pT spectra measured near central rapidity in the range 0.5 < pT < 20 GeV/c exhibit a weak pseudorapidity dependence. The nuclear modification factor RpPb is consistent with unity for pT above 2 GeV/c. This measurement indicates that the strong suppression of hadron production at high pT observed in Pb–Pb collisi...The transverse momentum (pT) distribution of primary charged particles is measured in non-singlediffractive p–Pb collisions at √sNN = 5.02 TeV with the ALICE detector at the LHC. The pT spectra measured near central rapidity in the range 0.5 < pT < 20 GeV/c exhibit a weak pseudorapidity dependence. The nuclear modification factor RpPb is consistent with unity for pT above 2 GeV/c. This measurement indicates that the strong suppression of hadron production at high pT observed in Pb–Pb collisions at the LHC is not due to an initial-state effect. The measurement is compared to theoretical calculations.» weiterlesen» einklappen
