Non-flow correlations in a cluster model
arXiv:0812.1176 · doi:10.1103/PhysRevC.81.064905
Abstract
We derive analytical forms for nonflow contributions from cluster correlation to the measurement of two-particle elliptic flow (v2{2}). We estimate nonflow contribution from rho->pi+pi decays and find it is negative but not a major contributor to the nonflow effect in v2{2}. We also estimate nonflow contribution from the recent STAR measurement of two-particle angular correlations.
