Title: Understanding the Emission Duration through Femtoscopy and Imaging

Abstract

We investigate the role of lifetime effects in femtoscopy at RHIC. We find the long emission durations do not necessarily lead to large outward radii. Within the Core-Halo model, we show that resonance induced halos lead to non-Gaussian tails in the two particle source. We note that the emission duration of the system can mask this tail. We illustrate the strong differences between the two-particle source shape in the side and outwards directions in the presence of a lifetime effect. We comment on the observability of these lifetime induced tails through source imaging.
