QCD Calculations of Pion Electromagnetic and Transition Form Factors

High Energy Physics - Phenomenology 2017-08-23 v2

Abstract

A short review is given of calculations of the pion electromagnetic and transition form factors within the framework of quantum chromodynamics. It is argued that both the perturbative and nonperturbative aspects of the Q^2 dependence of these form factors are rather well understood in QCD. However, new experimental data at higher Q^2 would be extremely helpful for detailed tests of the transition to the regime where the pQCD hard contribution plays the dominant role.
