Source imaging methodology is used to provide a three-dimensional two-pion source function for midrapidity pion pairs with p T < 70 MeV/c in central (0-7%) Pb + Pb collisions at √ s NN = 17.3 GeV.Prominent non-Gaussian tails are observed in the pion pair transverse momentum (outward) and in the beam (longitudinal) directions. Model calculations reproduce them with the assumption of Bjorken longitudinal boost invariance and transverse flow blast-wave dynamics; they also yield a proper time for breakup and emission duration for the pion source.

We introduce the coalescence va, iables, a set of three boost.invariant kinematic quantities which may be used in analyzing n-particle correlations. These variables characterize the invariant mass of an n-particle system and in three directions and separate the timelike and spacelike characteristics of the source. The analytic Kolehmah._en-Gyula_sy model is generalized to give two, three, and four-particle correlation functions, with coherence and Coulomb corrections applied to the basic formalism. We demonstrate the relation of the coalescence variables to the radius and duration of the source, and find that for sufficiently large transverse radii, Coulomb effects can suppress the structure of the Hanb,lry-Brown-Twiss correlations so that no significant information on source size can be obtained.
