Near Threshold Pion Electroproduction at High Q2

Puneet Khetarpal
Rensselaer Polytechnic Institute

Near threshold pion electroprocution as a function of Q2 can be written in 
terms of new form factors.  These new generalized form factors G1piN and G2piN 
have been predicted using light cone sum rules in the chiral limit for the 
reactions ep -> eNpi in the Q2 1 - 10 GeV2 range.  An experiment at Jefferson 
Lab has been conducted using the CLAS spectrometer to measure near threshold 
pion electroproduction as a function of Q2.  Preliminary differential cross 
sections will be presented.
