Pion interferometry in Au+Au collisions at sNN=200GeV Academic Article uri icon

abstract

  • We present a systematic analysis of two-pion interferometry in Au+Au collisions at √sNN = 200 GeV using the STAR detector at Relativistic Heavy Ion Collider. We extract the Hanbury-Brown and Twiss radii and study their multiplicity, transverse momentum, and azimuthal angle dependence. The Gaussianness of the correlation function is studied. Estimates of the geometrical and dynamical structure of the freeze-out source are extracted by fits with blast-wave parametrizations. The expansion of the source and its relation with the initial energy density distribution is studied. ©2005 The American Physical Society.
