Pion Interferometry for Cylindrical Quark-Gluon Plasma Evolution Sources

  • We examine the two-pion Hanbury-Brown-Twiss (HBT) interferometry for the expanding sources of quark-gluon plasma evolution with the Bjorken cylinder geometry.The two-pion HBT correlation functions are calculated using quantum probability amplitudes in a path-integral formalism and the HBT radius is extracted both for the expanding source and the static source.We find that the HBT radius for the freeze-out emission case is substantially greater than that for the without absorption of multiple scattering case. The expanding velocity of the source leads to a smaller HBT radius. The effect of expanding velocity for the Bjorken cylinder source with zero width of the transition temperature is smaller than those of the corresponding spherical source.

Abstract: We examine the two-pion Hanbury-Brown-Twiss (HBT) interferometry for the expanding sources of quark-gluon plasma evolution with the Bjorken cylinder geometry.The two-pion HBT correlation functions are calculated using quantum probability amplitudes in a path-integral formalism and the HBT radius is extracted both for the expanding source and the static source.We find that the HBT radius for the freeze-out emission case is substantially greater than that for the without absorption of multiple scattering case. The expanding velocity of the source leads to a smaller HBT radius. The effect of expanding velocity for the Bjorken cylinder source with zero width of the transition temperature is smaller than those of the corresponding spherical source.
