Non-Gaussian Effects in Identical Pion Correlation Function at STAR
arXiv:nucl-ex/0511053 · doi:10.1063/1.2197466
Abstract
Preliminary femtoscopic results on identical pions from high statistics data set of Au+Au collisions at sqrt{s_NN}=200 GeV taken during the fourth RHIC run are presented. The measured three-dimensional correlation function is studied at low relative momenta using the Gaussian parametrization and the Levy stable parametrization. The latter is expected to better describe the data. As the results show, both parametrizations underestimate the peak of the measured correlation function equally.
