Abstract

Emission source functions are extracted from correlation functions constructed from charged pions produced at midrapidity in Au+Au collisions at √sNN=200 GeV. The source parameters extracted from these functions at low kT give first indications of a long tail for the pion emission source. The source extension cannot be explained solely by simple kinematic considerations. The possible role of a halo of secondary pions from resonance emissions is explored.
