Dependence on Collision Centrality of Charged Particle Production at SNN=2.76TeV

The ALICE collaboration provides data for particle collisions. With the help of Glauber model calculation, the collisions are categorized in to different centralities. Then, a tracklet algorithm is used on each of the centrality category. The relationship between charged particle production and collision centrality is derived, and the result is in agreement with similar work done previously.
