We report the measured transverse momentum (pT) spectra of primary charged
particles from pp, p-Pb and Pb-Pb collisions at a center-of-mass energy √sNN = 5.02 TeV
in the kinematic range of 0.15 < pT < 50 GeV/c and |η| < 0.8. A significant improvement
of systematic uncertainties motivated the reanalysis of data in pp and Pb-Pb collisions at
√sNN = 2.76 TeV, as well as in p-Pb collisions at √sNN = 5.02 TeV, which is also presented.
Spectra from Pb-Pb collisions are presented in nine centrality intervals and are compared
to a reference spectrum from pp collisions scaled by the number of binary nucleon-nucleon
collisions. For central collisions, the pT spectra are suppressed by more than a factor of 7
around 6–7 GeV/c with a significant reduction in suppression towards higher momenta up to
30 GeV/c. The nuclear modification factor RpPb, constructed from the pp and p-Pb spectra
measured at the same collision energy, is consistent with unity above 8 GeV/c. While the
spectra in both pp and Pb-Pb collisions are substantially harder at √sNN = 5.02 TeV
compared to 2.76 TeV, the nuclear modification factors show no significant collision energy
dependence. The obtained results should provide further constraints on the parton energy
loss calculations to determine the transport properties of the hot and dense QCD matter.

Abstract
We report the measured transverse momentum (pT) spectra of primary charged
particles from pp, p-Pb and Pb-Pb collisions at a center-of-mass energy √sNN = 5.02 TeV
in the kinematic range of 0.15 < pT < 50 GeV/c and |η| < 0.8. A significant improvement
of systematic uncertainties motivated the reanalysis of data in pp and Pb-Pb collisions at
√sNN = 2.76 TeV, as well as in p-Pb collisions at √sNN = 5.02 TeV, which is also presented.
Spectra from Pb-Pb collisions are presented in nine centrality intervals and are compared
to a reference spectrum from pp collisions scaled by the number of binary nucleon-nucleon
collisions. For central collisions, the pT spectra are suppressed by more than a factor of 7
around 6–7 GeV/c with a significant reduction in suppression towards higher momenta up to
30 GeV/c. The nuclear modification factor RpPb, constructed from the pp and p-Pb spectra
measured at the same collision energy, is consistent with unity above 8 GeV/c. While the
spectra in both pp and Pb-Pb collisions are substantially harder at √sNN = 5.02 TeV
compared to 2.76 TeV, the nuclear modification factors show no significant collision energy
dependence. The obtained results should provide further constraints on the parton energy
loss calculations to determine the transport properties of the hot and dense QCD matter.

Il report seguente simula gli indicatori relativi alla propria produzione scientifica in relazione alle soglie ASN 2023-2025 del proprio SC/SSD. Si ricorda che il superamento dei valori soglia (almeno 2 su 3) è requisito necessario ma non sufficiente al conseguimento dell'abilitazione. La simulazione si basa sui dati IRIS e sugli indicatori bibliometrici alla data indicata e non tiene conto di eventuali periodi di congedo obbligatorio, che in sede di domanda ASN danno diritto a incrementi percentuali dei valori. La simulazione può differire dall'esito di un’eventuale domanda ASN sia per errori di catalogazione e/o dati mancanti in IRIS, sia per la variabilità dei dati bibliometrici nel tempo. Si consideri che Anvur calcola i valori degli indicatori all'ultima data utile per la presentazione delle domande.
La presente simulazione è stata realizzata sulla base delle specifiche raccolte sul tavolo ER del Focus Group IRIS coordinato dall’Università di Modena e Reggio Emilia e delle regole riportate nel DM 589/2018 e allegata Tabella A. Cineca, l’Università di Modena e Reggio Emilia e il Focus Group IRIS non si assumono alcuna responsabilità in merito all’uso che il diretto interessato o terzi faranno della simulazione. Si specifica inoltre che la simulazione contiene calcoli effettuati con dati e algoritmi di pubblico dominio e deve quindi essere considerata come un mero ausilio al calcolo svolgibile manualmente o con strumenti equivalenti.
