Exclusive J/ψ photoproduction off protons in ultra-peripheral p-Pb collisions at sNN−−−√=5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We present the first measurement at the LHC of exclusive J=ψ photoproduction off protons, in pffiffiffiffiffiffiffi ultraperipheral proton-lead collisions at sNN 1⁄4 5.02 TeV. Events are selected with a dimuon pair produced either in the rapidity interval, in the laboratory frame, 2.5 < y < 4 (p-Pb) or −3.6 < y < −2.6 (Pb-p), and no other particles observed in the ALICE acceptance. The measured cross sections σðγ þ p → J=ψ þ pÞ are 33.2 2.2ðstatÞ 3.2ðsystÞ 0.7ðtheorÞ nb in p-Pb and 284 36ðstatÞþ27ðsystÞ −32 26ðtheorÞ nb in Pb-p collisions. We measure this process up to about 700 GeV in the γp ...Daha fazlası

Suppression of Υ (1S) at forward rapidity in Pb–Pb collisions at √sNN = 2.76 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We report on the measurement of the inclusive Υ (1S) production in Pb–Pb collisions at √sNN = 2.76 TeV carried out at forward rapidity (2.5 < y < 4) and down to zero transverse momentum using its μ+μ− decay channel with the ALICE detector at the Large Hadron Collider. A strong suppression of the inclusive Υ(1S) yield is observed with respect to pp collisions scaled by the number of independent nucleon– nucleon collisions. The nuclear modification factor, for events in the 0–90% centrality range, amounts to 0.30 ± 0.05(stat) ± 0.04(syst). The observed Υ (1S) suppression tends to increase with t ...Daha fazlası

Multiplicity dependence of jet-like two-particle correlation structures in p–Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

Two-particle angular correlations between unidentified charged trigger and associated particles are measured by the ALICE detector in p–Pb collisions at a nucleon–nucleon centre-of-mass energy of 5.02 TeV. The transverse-momentum range 0.7 < pT,assoc < pT,trig < 5.0 GeV/c is examined, to include correlations induced by jets originating from low momentum-transfer scatterings (minijets). The correlations expressed as associated yield per trigger particle are obtained in the pseudorapidity range |η| < 0.9. The near-side long-range pseudorapidity correlations observed in high-multiplicity p–Pb col ...Daha fazlası
