Azimuthal anisotropy of charged jet production in √sNN = 2.76 TeV Pb–Pb collisions

KARASU UYSAL, Ayben | ALICE Collaboration

We present measurements of the azimuthal dependence of charged jet production in central and semi- central √sNN = 2.76 TeV Pb–Pb collisions with respect to the second harmonic event plane, quantified as vch jet. Jet finding is performed employing the anti-kT algorithm with a resolution parameter R = 0.2 2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different ...Daha fazlası

D-meson azimuthal anisotropy in mid-central Pb–Pb collisions at √ sNN = 5.02 TeV

KARASU UYSAL, Ayben | ALICE Collaboration

The azimuthal anisotropy coefficient v2 of prompt D0, Dþ, D þ, and Dþs mesons was measured in sNN 1⁄4 5.02 TeV, with the ALICE detector at the LHC. The D mesons were reconstructed via their hadronic decays at midrapidity, jyj < 0.8, in the transverse momentum interval 1 < pT < 24 GeV/c. The measured D-meson v2 has similar values as that of charged pions. The Dþs v2, measured for the first time, is found to be compatible with that of nonstrange D mesons. The measurements are compared with theoretical calculations of charm-quark transport in a hydrodynamically expanding medium and have the poten ...Daha fazlası
