Azimuthal anisotropy of long-range correlations at LHC energy in Monte Carlo model with string fusion

Research output: Contribution to journalArticlepeer-review

Abstract

Long-range multiplicity correlations in intervals separated in pseudorapidity and azimuth are studied in the framework of string fusion approach. We applied a Monte Carlo model, in which the string configurations in the transverse plane and rapidity are simulating event-by-event. The string interaction is realized in the lattice string fusion approach with introduction of a grid in the transverse plane. We assumed that the azimuthal anisotropy of particle production is caused by parton energy loss traveling trough the media formed by clusters of fused strings : ∆p t /∆x = −α(p t √ η) 2/3 , where η is a string density. In the cellular approach the Bresenham’s line algorithm has been applied.It is obtained that in AA collisions, the parton energy loss seems to play considerable role, in particular, by providing large contribution to the correlation of mean transverse momentum with multiplicity. The developed approach provides non-zero values flows in p-Pb collisions at LHC energies and produces the pattern simi
