Evolution of pion HBT radii from RHIC to LHC -- Predictions from ideal hydrodynamics
arXiv:0707.1898 · doi:10.1088/0954-3899/34/11/002
Abstract
We present hydrodynamic predictions for the charged pion HBT radii for a range of initial conditions covering those presumably reached in Pb+Pb collisions at the LHC. We study central (b=0) and semi-central (b=7fm) collisions and show the expected increase of the HBT radii and their azimuthal oscillations. The predicted trends in the oscillation amplitudes reflect a change of the final source shape from out-of-plane to in-plane deformation as the initial entropy density is increased.
