Search for collectivity with azimuthal J/ψ-hadron correlations in high multiplicity p–Pb collisions at √sNN = 5.02 and 8.16 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

We present a measurement of azimuthal correlations between inclusive J/ψ and charged hadrons in p-Pb collisions recorded with the ALICE detector at the CERN LHC. The J/ψ are reconstructed at forward (p-going, 2.03 < y < 3.53) and backward (Pb-going, −4.46 < y < −2.96) rapidity via their μ+μ− decay channel, while the charged hadrons are reconstructed at mid-rapidity (|η| < 1.8). The correlations are expressed in terms of associated charged-hadron yields per J/ψ trigger. A rapidity gap of at least 1.5 units is required between the trigger J/ψ and the associated charged hadrons. Possible correlat ...Daha fazlası

Multiparticle azimuthal correlations in p-Pb and Pb-Pb collisions at the CERN Large Hadron Collider

KARASU UYSAL, Ayben | ALICE Collaboration

Measurements of multiparticle azimuthal correlations (cumulants) for charged particles in p-Pb at √sNN = 5.02 TeV and Pb-Pb at √sNN = 2.76 TeV collisions are presented. They help address the question of whether there is evidence for global, flowlike, azimuthal correlations in the p-Pb system. Comparisons are made to measurements from the larger Pb-Pb system, where such evidence is established. In particular, the second harmonic two-particle cumulants are found to decrease with multiplicity, characteristic of a dominance of few-particle correlations in p-Pb collisions. However, when a |η| gap i ...Daha fazlası

Measurement of azimuthal correlations of D mesons with charged particles in pp collisions at √s = 7 TeV and p–Pb collisions at √sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The azimuthal correlations of D mesons with charged particles were measured with the ALICE appara- tus in pp collisions at √s = 7 TeV and p–Pb collisions at √sNN = 5.02 TeV at the Large Hadron Collider. D0 , D+ , and D∗+ mesons and their charge conjugates with transverse momentum 3 < pT < 16 GeV/c and rapidity in the nucleon- nucleon centre-of-mass system | ycms | < 0.5 (pp collisions) and −0.96 < ycms < 0.04 (p–Pb collisions) were corre- lated to charged particles with pT > 0.3 GeV/c. The yield of charged particles in the correlation peak induced by the jet containing the D meson and the peak ...Daha fazlası
