Findings

Successful description of hadronic and asymptotic regions

Introduction of a new Regge fermion exchange mechanism

Enhanced understanding of pion form factor behavior

Abstract

We consider the electromagnetic and transition pion form factors. Using dispersion relations we simultaneously describe both the hadronic, time-like region and the asymptotic region of large energy-momentum transfer. For the latter we propose a novel mechanism of Regge fermion exchange.
