Transverse momentum fluctuations and percolation of strings
The peculiar behaviour of the transverse momentum fluctuations with the centrality of the collision shown by the Relativistic Heavy Ion Collider data is naturally explained by the percolation of strings. In this framework, the pT fluctuations are nothing but fluctuations on the number of overlapping strings that form clusters in a heavy ion collision. According to this idea, the fluctuations sh...
متن کاملInfluence of Impact Parameter Fluctuations on Transverse Momentum Fluctuations
The preliminary NA49 results on the energy dependence of transverse momentum fluctuations over the whole Super Proton Synchrotron (SPS) energy range exhibit an unexpected effect. The ΦpT fluctuation measure used by the NA49 experiment manifests a different behavior for different charge combinations. Whereas the ΦpT is consistent with zero and independent of energy for negatively charged particl...
متن کاملFluctuations and Transverse Momentum Distributions in the Color Clustering Approach
We present our results on transverse momentum fluctuations, multiplicity fluctuations and transverse momentum distributions for baryons and mesons in the framework of the clustering of color sources. We determine under what conditions the initial state configurations can lead to color connection, and more specifically, if variations of the initial state can lead to a transition from disconnecte...
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 کاملProbing Quark Gluon Liquid Using Transverse Momentum Fluctuations
Liquids exhibit shorter correlation lengths than gases. Correlation and fluctuation measurements can therefore reveal the state – liquid or gaseous – of the matter produced in heavy ion collisions, but we must first sort out the ion-collision effects that also contribute. Experiments show that dynamic fluctuations of the transverse momentum are roughly independent of beam energy, but increase a...
