Theoretical analysis of the pp¯→π0e+e− process within a Regge framework

subject

description

Abstract We study the annihilation process p p ¯ → π 0 e + e − within a Regge framework, as a means to provide constraints on timelike nucleon form factors. We present results for the e + e − angular distributions and the differential cross sections in kinematics which will be accessible by PANDA@FAIR. To check the consistency of the model, we first test the approach on the process of real photon production, p ¯ p → π 0 γ , where data in the energy range of 2.911 GeV ⩽ s ⩽ 3.686 GeV exist. We find that a Regge pole model is able to well reproduce the available data. The analysis is then extended to a timelike virtual photon in the final state.
