Title: Transport Model Study of HBT at RHIC

Abstract

The pion interferometry at the Relativistic Heavy Ion Collider (RHIC) has been studied in a multiphase transport (AMPT) model that includes both initial partonic and final hadronic interactions. It was found that the two-pion correlation function was sensitive to the magnitude of the cross sections for parton scattering in the partonic matter. Also, the emission source of pions from the AMPT model is non-Gaussian with strong space-time and momentum correlations as well as a large halo around the central core, leading to source radii that can be more than twice larger than the radius parameters extracted from a Gaussian fit to the correlation function.

  • We review the significant difference in the ratio R{sub out}/R{sub side} between experiment and theory in heavy-ion collisions at RHIC. This ratio is expected to be strongly correlated with the pion emission duration. Hydrodynamic models typically calculate a value that approximately equal to 1.5 and moderately dependent on k{sub T} whereas the experiments report a value close to unity and independent of k{sub T}. We review those calculations in which systematic variations in the theoretical assumptions were reported. We find that the scenario of second order phase transition or cross-over has been given insufficient attention, and may play an importantmore » role in resolving this discrepancy.« less
  • We present a relativistic quantum wave-mechanical optical model treatment of the opacity and refractive effects of pions emerging from a hot dense expanding source. The Klein-Gordon equation with Bjorken-cylinder geometry is solved for distorted waves representing the emerging pions. These waves are combined with a hydro-inspired pion source function to predict HBT radii and pion spectra. The model, when using a very deep potential well, has produced excellent HBT radii and spectrum fits to RHIC {radical}(s{sub NN}) = 200 GeV Au+Au data from STAR, reproducing the observed small source sizes, RO/RS {approx_equal} 1, the low-momentum behavior of the radii, andmore » the pion spectrum in shape and magnitude. The calculations represent a new tool for investigating the presence and characteristics of chiral symmetry restoration in heavy ion collisions.« less
  • The pseudo-rapidity dependence of the elliptic flow at various excitation energies measured by the PHOBOS Collaboration in Au+Au collisions at RHIC is one of the surprising results that has not been explained before in terms of hydrodynamical models. Here we show that these data are in agreement with theoretical predictions and satisfy the universal scaling relation predicted by the Buda-Lund hydrodynamical model, based on exact solutions of perfect fluid hydrodynamics. We also show a theoretical prediction on the rapidity and transverse momentum scaling of the HBT radii measured in heavy ion collisions, based on the Buda-Lund model.
  • Preliminary azimuthal pion HBT results obtained from a hadronic rescattering model are compared with experimental RHIC results. The model is also used to obtain preliminary predictions for radial and elliptic flow and pion HBT parameters for LHC Pb+Pb collisions. A test of the calculational method used for the rescattering code is shown using the subdivision method.
  • Typical features of the transport equation derived in a previous paper are studied in the frame of a one-dimensional model. The optical-model Green's function is constructed, and the mean free path is evaluated numerically. The domain of validity of the semiclassical approximation to the transport equation is evaluated, the significance of conserving approximations is pointed out. For strong absorption (short mean free path) it is shown that quantum fluctuations caused by the uncertainty principle are important. Approximation methods are introduced and tested numerically.
