# Longitudinal Fluctuations in Heavy-Ion Collisions with the ALICE Detector

Description

Longitudinal fluctuations in A-A collisions are decomposed using Legendre polynomials in the final particle pseudorapidity distribution. The first order longitudinal coefficient, a1, is computed event by event for a single particle distribution for charged tracks, and positive and negative only tracks. Soft tracks were analyzed for 0.2 < pT < 2.0 GeV/c. The pseudorapidity window used is [-0.8,0.8]. Results of a1 are presented for Run 2 Xe-Xe (sqrt(sNN)=5.44TeV) and Pb-Pb (sqrt(sNN)=5.02TeV) data and MC HIJING. A strong forward-backward asymmetry is observed, and the MC HIJING is disfavored when describing this asymmetry.
