We present the measurement of a new set of jet shape observables for track- based jets in central Pb-Pb collisions at √sNN = 2.76 TeV. The set of jet shapes includes the first radial moment or angularity, g, the momentum dispersion, pTD, and the differ- ence between the leading and sub-leading constituent track transverse momentum, LeSub. These observables provide complementary information on the jet fragmentation and can constrain different aspects of the theoretical description of jet-medium interactions. The jet shapes were measured for a small resolution parameter R = 0.2 and were fully co ...Daha fazlası
We report the measured transverse momentum (pT) spectra of primary charged particles from pp, p-Pb and Pb-Pb collisions at a center-of-mass energy √sNN = 5.02 TeV in the kinematic range of 0.15 < pT < 50 GeV/c and |η| < 0.8. A significant improvement of systematic uncertainties motivated the reanalysis of data in pp and Pb-Pb collisions at √sNN = 2.76 TeV, as well as in p-Pb collisions at √sNN = 5.02 TeV, which is also presented. Spectra from Pb-Pb collisions are presented in nine centrality intervals and are compared to a reference spectrum from pp collisions scaled by the number of binary nu ...Daha fazlası
The elliptic (v2), triangular (v3), and quadrangular (v4) flow coefficients of π±, K±, p+p, Λ+Λ, K0S, and the φ-meson are measured in Pb-Pb collisions at √sNN = 5.02 TeV. Results obtained with the scalar product method are reported for the rapidity range |y| < 0.5 as a function of transverse momentum, pT, at different collision centrality intervals between 0–70%, including ultra-central (0–1%) collisions for π±, K±, and p + p. For pT < 3 GeV/c, the flow coefficients exhibit a particle mass dependence. At intermediate transverse momenta (3 < pT < 8–10 GeV/c), particles show an approximate group ...Daha fazlası
Measurements of anisotropic flow coefficients with two- and multi-particle cu- mulants for inclusive charged particles in Pb–Pb collisions at √sNN = 5.02 and 2.76 TeV are reported in the pseudorapidity range |η| < 0.8 and transverse momentum 0.2 < pT < 50 GeV/c. The full data sample collected by the ALICE detector in 2015 (2010), corre- sponding to an integrated luminosity of 12.7 (2.0) μb−1 in the centrality range 0–80%, is analysed. Flow coefficients up to the sixth flow harmonic (v6) are reported and a de- tailed comparison among results at the two energies is carried out. The pT dependence ...Daha fazlası
Inclusive J/ψ production is studied in p-Pb interactions at a centre-of-mass energy per nucleon-nucleon collision sNN−−−√=8.16 TeV, using the ALICE detector at the CERN LHC. The J/ψ meson is reconstructed, via its decay to a muon pair, in the centre-of-mass rapidity intervals 2.03< ycms< 3.53 and −4.46< ycms< −2.96, where positive and negative ycms refer to the p-going and Pb-going direction, respectively. The transverse momentum coverage is pT< 20 GeV/c. In this paper, ycms- and pT-differential cross sections for inclusive J/ψ production are presented, and the corresponding nuclear modificati ...Daha fazlası
