Exclusive Neutral Pion Electroproduction in the Deeply Virtual Regime

Understand

We present measurements of the ep->ep pi^0 cross section extracted at two values of four-momentum transfer Q^2=1.9 GeV^2 and Q^2=2.3 GeV^2 at Jefferson Lab Hall A.

• The kinematic range allows to study the evolution of the extracted hadronic tensor as a function of Q^2 and W.
• Results will be confronted with Regge inspired calculations and GPD predictions.
• An intepretation of our data within the framework of semi-inclusive deep inelastic scattering has also been attempted.
