Measurement of quantumstatistical correlation functions in high energy nuclear physics is an important tool to investigate the QCD phase diagram. It may be used to search for the critical point, and also to understand underlying processes such as in-medium mass modifications or partially coherent particle production. Furthermore, the measurements of the femtoscopic correlation functions shed light on the space-time structure of particle production. Consequently, the precise measurements and description of the correlation functions are essential. The shape of two-pion Bose-Einstein correlation functions were often assumed to be Gaussian, but the recent precision of the experiments reveals that the statistically correct assumption is the more general Lévy-distribution. In this paper we present the recent results of the measurements of two-pion Lévy-stable Bose-Einstein correlation functions in Au+Au collisions at PHENIX
