Abstract:
The modern relativistic nuclear collision experiments (e.g. AGS, RHIC, LHC, FAIR) aim to reveal the QGP properties [1-4]. The Equation of State studied by means of anisotropic flow is one way to find information about the initial geometry fluctuations and viscosity of participant nuclear matter. Using a jet-finding algorithm and the global analysis by transverse sphericity formalism we extracted properties of anisotropic flow in UrQMD simulated collisions.
