Description
Bose-Einstein correlations of identical hadrons reveal information about hadron
creation from the sQGP formed in ultrarelativistic heavy ion collisions. The
measurement of three particle correlations may in particular shed light on
hadron creation mechanisms beyond thermal/chaotic emission. In this poster we
show the status of PHENIX measurements of three pion correlations as a function of momentum
differences within the triplets. We will analyze their shape through the assumption
of Levy sources and a proper treatment of the Coulomb interaction within the
triplets. We plan to determine Levy parameters scale ($R$), shape ($\alpha$) and three
particle correlation strength ($\lambda_3$), where the latter, together with two
particle correlation strength $\lambda_2$, encodes information about hadron
creation mechanisms. From a consistent analysis of two- and three-particle
correlation strength we may be able to establish an experimental measure of thermalization and
coherence in the source.
