Exclusive neutral pion electroproduction in the deeply virtual regime

We present measurements of the ep → epπ0 [ep pi superscript 0] cross section extracted at two values of four-momentum transfer Q2 = 1.9 GeV2 [Q superscript 2 = 1.9 GeV superscript 2] and Q2 = 2.3 GeV2 [Q superscript 2 = 2.3 GeV superscript 2] at Jefferson Lab Hall A. The kinematic range allows one t...

Description
Summary:We present measurements of the ep → epπ0 [ep pi superscript 0] cross section extracted at two values of four-momentum transfer Q2 = 1.9 GeV2 [Q superscript 2 = 1.9 GeV superscript 2] and Q2 = 2.3 GeV2 [Q superscript 2 = 2.3 GeV superscript 2] at Jefferson Lab Hall A. The kinematic range allows one to study the evolution of the extracted cross section as a function of Q2 [Q superscript 2] 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.
