abstract

  • The resonant P33 single-pion electroproduction multipole amplitude S1+(3/2)(q2) and the ΔNγ scalar form factor GC*(q2) are calculated nonperturbatively in terms of the well-known nucleon form factors gA(q2) and GEV(q2). Results are in good agreement with experiment. Our treatment is completely relativistic with current conservation guaranteed. Assuming the usual dipole behavior for gA(q2) and GEV(q2), we confirm that GC*(q2) falls off asymptotically at the rate q-6 as expected in perturbative QCD. © 1994 The American Physical Society.
