Splitting function in pp and PbPb collisions at 5.02 TeV
A measurement of the splitting function in pp and PbPb collisions at a center of mass energy of 5.02 TeV per nucleon pair is presented. The virtuality evolution of partons traversing the hot QCD medium created in a heavy ion collision is potentially modified due to interactions with the color charges of the medium. This measurement probes this phenomenon by measuring the generalized fragmentati...
متن کاملEvidence for Statistical Production of J/ψ Mesons in Nuclear Collisions at the CERN SPS
The hypothesis of statistical production of J/ψ mesons at hadronization is formulated and checked against experimental data. It explains in the natural way the observed scaling behavior of the J/ψ to pion ratio at the CERN SPS energies. Using the multiplicities of J/ψ and η mesons the hadronization temperature TH ∼= 170 MeV is found, which agrees well with the previous estimates of the temperat...
متن کاملElliptic flow and nuclear modification factors of D-mesons at FAIR in a Hybrid-Langevin approach
The Compressed Baryonic Matter (CBM) experiment at the Facility for Anti-proton and Ion Research (FAIR) will provide new possibilities for charm-quark (D-meson) observables in heavy-ion collisions at low collision energies and high baryon densities. To predict the collective flow and nuclear modification factors of charm quarks in this environment, we apply a Langevin approach for the transport...
متن کاملObservation of sequential Υ suppression in PbPb collisions.
The suppression of the individual Υ(nS) states in PbPb collisions with respect to their yields in pp data has been measured. The PbPb and pp data sets used in the analysis correspond to integrated luminosities of 150 μb(-1) and 230 nb(-1), respectively, collected in 2011 by the CMS experiment at the LHC, at a center-of-mass energy per nucleon pair of 2.76 TeV. The Υ(nS) yields are measured from...
متن کاملMeasurement of higher-order harmonic azimuthal anisotropy in PbPb collisions at √ sNN = 2.76 TeV
Measurements are presented by the CMS Collaboration at the Large Hadron Collider (LHC) of the higher-order harmonic coefficients that describe the azimuthal anisotropy of charged particles emitted in √ sNN = 2.76 TeV PbPb collisions. Expressed in terms of the Fourier components of the azimuthal distribution, the n = 3–6 harmonic coefficients are presented for charged particles as a function of ...
