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.

| 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. |
