abstract:

Di-hadron correlations are very important for the understanding of heavy ion collisions, especially the initial conditions and the properties of the Quark-Gluon-Plasma (QGP). Measurements of charged di-hadron angular correlations are presented in proton-proton (pp), proton-Lead (pPb) and Lead-Lead (PbPb) collisions, over a broad range of pseudorapidity and azimuthal angle, using the CMS detector at the LHC. A Fourier analysis of the long-range correlations are studied and discussed in the context of CMS measurements of higher order flow coefficients in pPb and PbPb. Direct comparisons of these measurements in pp, pPb and PbPb as a function of transverse momentum and charged particle multiplicity will be presented.
