We present measurements of the ep→epπ0 cross section extracted at two values of four-momentum transfer Q2=1.9GeV2 and Q2=2.3GeV2 at Jefferson Lab Hall A. The kinematic range allows one to study the evolution of the extracted cross section as a function of Q2 and W. Results are confronted with Regge-inspired calculations and GPD predictions. An intepretation of our data within the framework of semi-inclusive deep inelastic scattering is also discussed.
