Event-by-Event Fluctuations of Transverse Momentum and Multiparticle Clusters in Relativistic Heavy-Ion Collisions
This paper is based on our recent analysis [1] of the eventby-event fluctuations of the mean transverse-momentum measured by PHENIX [2] and STAR [3, 4] Collaborations at RHIC. The discussed new data has extended our knowledge of the phenomena studied intensely in recent years [5–20]. One of the central issues in this field is whether the pT fluctuations at intermediate momenta result from jets ...
متن کاملEvent-by-event Fluctuations of Transverse Momentum in Elementary Collisions at 250 Gev/c
We present a study of event-by-event fluctuations of transverse momentum in πp and Kp collisions at 250 GeV/c and the corresponding PYTHIA Monte Carlo results for πp collisions. The dependence of Φpt on event and particle variables are investigated in detail. We find that Φpt are all negative for different average transverse momentum per event sample. The 〈pt〉N ∼ N correlation may not be the on...
متن کاملScale dependence of mean transverse momentum fluctuations at 158 AGeV
Non-statistical event-by-event fluctuations of mean transverse momentum, pT , have been proposed as a possible signature for the QCD phase transition, in particular for the critical point. A surprising finding was that a small but practically beam energy independent value was found for the broad energy range of 40 AGeV SPS beam up to top RHIC energy [1]. On the other hand, the fluctuations seem...
متن کاملEvidence for transverse-momentum- and pseudorapidity- dependent event-plane fluctuations in PbPb and pPb collisions
A systematic study of the factorization of long-range azimuthal two-particle correlations into a product of single-particle anisotropies is presented as a function of pT and η of both particles and as a function of the particle multiplicity in PbPb and pPb collisions. The data were taken with the CMS detector for PbPb collisions at √ sNN = 2.76 TeV and pPb collisions at√sNN = 5.02 TeV, covering...
متن کاملOn Transverse Momentum Event–by–Event Fluctuations in String Hadronic Models
Transverse momentum event–by–event fluctuations are studied within the string– hadronic model of high energy nuclear collisions, LUCIAE. Data on non–statistical pT fluctuations in p+p interactions are reproduced. Fluctuations of similar magnitude are predicted for nucleus–nucleus collisions, in contradiction to the preliminary NA49 results. The introduction of a string clustering mechanism (Fir...
