Title: Bose-Einstein correlations from 'within'

Abstract

We describe an attempt to model numerically Bose-Einstein correlations (BEC) from 'within', i.e., by using them as the most fundamental ingredient of some Monte Carlo event generator (MC) rather than considering them as a kind of (more or less important, depending on the actual situation) 'afterburner', which inevitably changes original physical content of the MC code used to model multiparticle production process.

  • Second-order time correlations of polaritons have been measured across the condensation threshold in a CdTe microcavity. The onset of Bose-Einstein condensation is marked by the disappearance of photon bunching, demonstrating the transition from a thermal-like state to a coherent state. Coherence is, however, degraded with increasing polariton density, most probably as a result of self-interaction within the condensate and scatterings with noncondensed excitons and polaritons. Such behavior clearly differentiates polariton Bose condensation from photon lasing.
  • Bose-Einstein correlations between charged pion and [ital K][sup +] pairs are calculated using the space-time and four-momentum distributions from relativistic quantum molecular dynamics for 200 GeV/nucleon [sup 32][ital S]+Pb and compared to pion correlation measurements from two CERN experiments. Good agreement is found. The predicted apparent radii from the [ital K][sup +] correlation functions are smaller than the corresponding pion radii.
  • In a second-generation two-particle correlation study of ultra-relativistic heavy-ion collisions, the NA35 TPC at the CERN SPS has been used to collect a high statistics data set of negative hadrons forward of rapidity 3 (nucleon-nucleon mid-rapidity) from centrally triggered E/A=200 GeV S + Au collisions. We present preliminary results on the evolution of the source size as a function of pair transverse momentum, as inferred from the two-particle correlation function, in the hope of elucidating dynamical information. In addition, for comparison we present predictions for this evolution based upon a microscopic phase space approach (RQMD).
  • An algorithm is presented to adjust the uncorrelated momentum vectors of identical bosons produced by models of relativistic heavy-ion collisions to reproduce two-body and three-body Bose-Einstein correlation functions. The method is used to study the quality of the three-body correlations predicted by calculations in which prescribed two-body correlation functions are fit and to study the effects on the two-body distributions when the three-body correlations help constrain the momentum vector adjustment procedure. {copyright} {ital 1996 The American Physical Society.}
  • Using a (3+1)-dimensional solution of the relativistic Euler-equations for Pb+Pb at 160A GeV, space-time extensions of kaon emission zones are calculated from space-time densities and compared to the inverse widths of two-kaon Bose-Einstein correlation functions. The comparison shows a satisfactory agreement and it is concluded that because of the Gaussian shape of the kaon correlation functions, the space-time parameters of the kaon source can be calculated directly from space-time densities. In the case of intensity interferometry of identical pions this simplification is not recommended when applying Gaussian fits because of the present strong effects of resonance decays. The whole discussionmore » is based on the assumption that hadron emission in ultrarelativistic heavy-ion collisions is purely chaotic or that coherence is at least negligible. {copyright} {ital 1997} {ital The American Physical Society}« less
