Measurement of the elliptic anisotropy of charged particles produced in PbPb collisions at √sNN=2.76 TeV

S. Chatrchyan, +2187 more
- 07 Jan 2013 - 
TL;DR: In this article, the anisotropy of the azimuthal distributions of charged particles produced in √s_(NN)=2.76 TeV PbPb collisions with the CMS experiment at the LHC is studied with the event plane method, two-and fourparticle cumulants, and Lee-Yang zeros.
