Tracklet Method Analysis on Particle Production Based on Centrality Dependence
* Author to whom correspondence should be addressed.
Abstract
This paper presents an analysis on a parametrization of ALICE open data on the Pb-Pb collisions at √sNN = 2.76TeV created by the Large Hadron Collider (LHC). We will use the tracklet method to calculate the differences in pseudorapidity values (∆η), generate ∆η distributions for different centrality ranges, and investigate the centrality dependence of the number of particles produced. This document presents findings of a negative correlation between centrality classes and the number of particles produced.
Keywords
