Signatures for flow effects in s**(1/2) = 200 GeV proton-proton collisions

A simple model based on relativistic geometry and final-state hadronic rescattering is used to predict pion source parameters extracted in two-pion femtoscopy studies of proton-proton collisions at s**(1/2) = 200 GeV. From studying the momentum and particle multiplicity dependences of these parameters in the context of this model and assuming a very short hadronization time, flow-like behavior is seen which resembles the flow behavior commonly observed in relativistic heavy-ion collisions.
