摘要
Near threshold pion electroproduction as a function of Q(2) can be written in terms of new form factors. These new generalized form factors G(1)(pi N) and G(2)(pi N) have been predicted using light cone sum rules in the chiral limit for the reactions ep -> eN pi in the Q(2) 1-10 GeV2 range. An experiment at Jefferson Lab has been conducted using the CLAS spectrometer to measure near threshold neutral pion electroproduction as a function of Q(2). Preliminary cross sections, S-wave multipoles and generalized form factors are presented.
