Multiplicity and transverse momentum dependence of two- and four-particle correlations in pPb and PbPb collisions

Original language description

Measurements of two- and four-particle angular correlations for charged particles emitted in pPb collisions are presented over a wide range in pseudorapidity and full azimuth. The data, corresponding to an integrated luminosity of approximately 31 nb(-1), were collected during the 2013 LHC pPb run at a nucleon-nucleon center-of-mass energy of 5.02 TeV by the CMS experiment. The results are compared to 2.76 TeV semi-peripheral PbPb collision data, collected during the 2011 PbPb run, covering a similar range of particle multiplicities. The observed correlations are characterized by the near-side (vertical bar Delta phi vertical bar approximate to 0) associated pair yields and the azimuthal anisotropy Fourier harmonics (nu(n)). The second-order (nu(2)) and third-order (v(3)) anisotropy harmonics are extracted using the two-particle azimuthal correlation technique. A four-particle correlation method is also applied to obtain the value of nu(2) and further explore the multi-particle nature
