10:00 - 11:00 Lanny Ray (Univ. of Texas) Simulating Two-Particle Correlations in Relativistic Heavy Ion Collisions An algorithm for generating two-particle correlations in the relative momentum space distributions of particles produced in simulated relativistic heavy ion collisions has been implemented in a computer code and used extensively in simulation studies by the STAR collaboration. Recently this code was modified in order to accommodate the much higher event multiplicities anticipated in Pb+Pb collisions at the LHC as will be measured with the ALICE detector. The basic simulation method, the experiences gained from use of this tool in the STAR-HBT data analysis effort, and application of the code for the LHC-ALICE experiment will be described. 11:00 - 11:30 Jan Pluta (Warsaw Univ. of Technology) HBT and FSI simulations for ALICE We discuss the physics which can be learnt from two-particle momentum correlations in heavy ion collisions at the LHC. The role of both identical particle HBT momentum correlations and non-identical particle FSI correlations is explained. Both are sensitive to different aspects of the space-time evolution. Topics include: event generation with HBT and FSI afterburners, Coulomb correction, the role of strong Final State Interactions. Also, for the environment of the ALICE detection system, we discuss the expected resolution and purity of the shape of the correlation function, and the possibility to observe some particular correlation effects. 3) 11:30 - 12:00 Discussion: input to ALICE-PPR
