Hard exclusive neutral pion production at Jefferson Lab Hall A
We present measurements of the ep {yields} ep{pi}{sup 0} cross section extracted at two values of four-momentum transfer Q{sup 2} = 1.9 GeV{sup 2} and Q{sup 2} = 2.3 GeV{sup 2} at Jefferson Lab Hall A. The kinematic range allows to study the evolution of the cross section as a function of Q{sup 2} and W. Results will be confronted with Regge inspired calculations and GPD predictions. An interpretation of our data within the framework of semi-inclusive deep inelastic scattering has also been attempted.
