520 | |a The inclusive J/ψ production has been studied in Pb-Pb and pp collisions at the centre-of-mass energy per nucleon pair sNN=5.02 TeV, using the ALICE detector at the CERN LHC. The J/ψ meson is reconstructed, in the centre-of-mass rapidity interval 2.5<y<4 and in the transverse-momentum range pT<12 GeV/c, via its decay to a muon pair. In this Letter, we present results on the inclusive J/ψ cross section in pp collisions at s=5.02 TeV and on the nuclear modification factor RAA. The latter is presented as a function of the centrality of the collision and, for central collisions, as a function of the transverse momentum pT of the J/ψ. The measured RAA values indicate a suppression of the J/ψ in nuclear collisions and are then compared to our previous results obtained in Pb-Pb collisions at sNN=2.76 TeV. The ratio of the RAA values at the two energies is also computed and compared to calculations of statistical and dynamical models. The numerical value of the ratio for central events (0-10% centrality) is 1.17±0.04(stat)±0.20(syst). In central events, as a function of pT, a slight increase of RAA with collision energy is visible in the region 2<pT<6 GeV/c. Theoretical calculations qualitatively describe the measurements, within uncertainties. | ||

Zimmermann [und weitere], The inclusive J/ψ production has been studied in Pb-Pb and pp collisions at the centre-of-mass energy per nucleon pair sNN=5.02 TeV, using the ALICE detector at the CERN LHC. The J/ψ meson is reconstructed, in the centre-of-mass rapidity interval 2.5<y<4 and in the transverse-momentum range pT<12 GeV/c, via its decay to a muon pair. In this Letter, we present results on the inclusive J/ψ cross section in pp collisions at s=5.02 TeV and on the nuclear modification factor RAA. The latter is presented as a function of the centrality of the collision and, for central collisions, as a function of the transverse momentum pT of the J/ψ. The measured RAA values indicate a suppression of the J/ψ in nuclear collisions and are then compared to our previous results obtained in Pb-Pb collisions at sNN=2.76 TeV. The ratio of the RAA values at the two energies is also computed and compared to calculations of statistical and dynamical models. The numerical value of the ratio for central events (0-10% centrality) is 1.17±0.04(stat)±0.20(syst). In central events, as a function of pT, a slight increase of RAA with collision energy is visible in the region 2<pT<6 GeV/c. Theoretical calculations qualitatively describe the measurements, within uncertainties., Adam, Jaroslav VerfasserIn (DE-588)1169407668 (DE-627)1034107259 (DE-576)51209859X aut, Angelov, Venelin VerfasserIn (DE-588)1168033594 (DE-627)1031739378 (DE-576)511347898 aut, Arslandok, Mesut 1983- VerfasserIn (DE-588)1154897648 (DE-627)1016244266 (DE-576)501308075 aut, Danisch, Meike 1989- VerfasserIn (DE-588)116803518X (DE-627)1031740236 (DE-576)511347901 aut, Deisting, Alexander 1989- VerfasserIn (DE-588)1154513815 (DE-627)1015806686 (DE-576)501055851 aut, Glässel, Peter 1943- VerfasserIn (DE-588)1145396682 (DE-627)1006532641 (DE-576)161124941 aut, Kim, Jiyoung VerfasserIn (DE-588)1168036607 (DE-627)1031740996 (DE-576)511347944 aut, Klewin, Sebastian 1988- VerfasserIn (DE-588)1168038472 (DE-627)1031742395 (DE-576)511347960 aut, Leardini, Lucia VerfasserIn (DE-588)1147989826 (DE-627)100747873X (DE-576)496125990 aut, Mercado Pérez, Jorge VerfasserIn (DE-588)13685253X (DE-627)587814438 (DE-576)301310459 aut, Oeschler, Helmut 1945-2017 VerfasserIn (DE-588)1165251833 (DE-627)1029374686 (DE-576)510325203 aut, Ohlson, Alice VerfasserIn (DE-588)1161747443 (DE-627)1025198476 (DE-576)506841731 aut, Pachmayer, Yvonne C. 1978- VerfasserIn (DE-588)136314643 (DE-627)579320073 (DE-576)300957858 aut, Reygers, Klaus 1969- VerfasserIn (DE-588)121899594 (DE-627)705695018 (DE-576)292945892 aut, Schicker, Rainer 1954- VerfasserIn (DE-588)1049567250 (DE-627)782323898 (DE-576)403559995 aut, Schmidt, Marten Ole 1990- VerfasserIn (DE-588)1168048370 (DE-627)1031746315 (DE-576)511347987 aut, Stachel, Johanna 1954- VerfasserIn (DE-588)1012800016 (DE-627)699791340 (DE-576)345952251 aut, Weiser, Dennis 1990- VerfasserIn (DE-588)1168049393 (DE-627)1031747117 (DE-576)511347995 aut, Wilkinson, Jeremy VerfasserIn (DE-588)1113604530 (DE-627)867653787 (DE-576)477012507 aut, Windelband, Bernd VerfasserIn (DE-588)1049522419 (DE-627)782236499 (DE-576)403526108 aut, Zimmermann, Alice VerfasserIn (DE-588)1049522427 (DE-627)782236502 (DE-576)403526094 aut, Enthalten in Physics letters / B Amsterdam : North-Holland Publ., 1967 766(2017), Seite 212-224 Online-Ressource (DE-627)266015360 (DE-600)1466612-1 (DE-576)07495993X 1873-2445 nnns, volume:766 year:2017 pages:212-224 extent:13, http://dx.doi.org/10.1016/j.physletb.2016.12.064 Verlag Resolving-System kostenfrei Volltext, http://www.sciencedirect.com/science/article/pii/S0370269317300102 Verlag kostenfrei Volltext, http://dx.doi.org/10.1016/j.physletb.2016.12.064 LFER, LFER epn:303194657X 2018-11-12T00:00:00Z |
