Near Threshold Pion Electroproduction at High Q2

Puneet Khetarpal

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.
