Does HBT measure the freeze-out source distribution?
Journal of Physics G: Nuclear and Particle Physics
It is generally assumed that as a result of multiple scattering, the source distribution measured in HBT interferometry corresponds to a chaotic source at freeze-out. This assumption is subject to question as effects of multiple scattering in HBT measurements must be investigated within a quantum-mechanical framework. Applying the Glauber multiple scattering theory at high energies and the optical model at lower energies, we find that multiple scattering leads to an effective HBT densitydoi:10.1088/0954-3899/30/8/057 fatcat:3wnefrk3nzbl3hmzjp3gxlf6om
