Exploring Lifetime Effects in Femtoscopy
arXiv:0705.1337 · doi:10.1103/PhysRevC.76.044906
Abstract
We investigate the role of lifetime effects from resonances and emission duration tails in femtoscopy at RHIC in two Blast-Wave models. We find the non-Gaussian components compare well with published source imaged data, but the value of R_out obtained from Gaussian fits is not insensitive to the non-Gaussian contributions when realistic acceptance cuts are applied to models.
