Two-particle differential transverse momentum and number density correlations in p-Pb collisions at 5.02 TeV and Pb-Pb collisions at 2.76 TeV at the CERN Large Hadron Collider

KARASU UYSAL, Ayben | ALICE Collaboration

We present measurements of two-particle differential number correlation functions R2 and transverse momen- tum correlation functions P2, obtained from p-Pb collisions at 5.02 TeV and Pb-Pb collisions at 2.76 TeV. The results are obtained by using charged particles in the pseudorapidity range |η| < 1.0 and transverse momentum range 0.2 < pT < 2.0 GeV/c as a function of pair separation in pseudorapidity, |η|, azimuthal angle φ, and for several charged-particle multiplicity classes. Measurements are carried out for like-sign and unlike-sign charged-particle pairs separately and combined to obtain ...Daha fazlası

Measurement of the production of charm jets tagged with D0 mesons in pp collisions at √s = 7 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The production of charm jets in proton-proton collisions at a center-of-mass √ energy of s = 7 TeV was measured with the ALICE detector at the CERN Large Hadron Collider. The measurement is based on a data sample corresponding to a total inte- grated luminosity of 6.23nb−1, collected using a minimum-bias trigger. Charm jets are identified by the presence of a D0 meson among their constituents. The D0 mesons are 0−+0 reconstructed from their hadronic decay D →K π . The D -meson tagged jets are reconstructed using tracks of charged particles (track-based jets) with the anti-kT algo- rithm in the ...Daha fazlası

Investigations of Anisotropic Flow Using Multiparticle Azimuthal Correlations in pp, p-Pb, Xe-Xe, and Pb-Pb Collisions at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

Measurements of anisotropic flow coefficients (vn) and their cross-correlations using two- and multiparticle cumulant methods are reported in collisions of pp at √ s = 13 TeV, p–Pb at √sNN = 5.02 TeV, Xe–Xe at √sNN = 5.44 TeV, and Pb–Pb at √sNN = 5.02 TeV recorded with the ALICE detector. The multiplicity dependence of vn is studied in a very wide range from 20 to 3000 particles produced in the mid-rapidity region |η| < 0.8 for the transverse momentum range 0.2 < pT < 3.0 GeV/c. An ordering of the coefficients v2 > v3 > v4 is found in pp and p–Pb collisions, similar to that seen in large colli ...Daha fazlası
