abstract
A parameter-free, nonperturbative calculation of the ΔNγ electromagnetic transition amplitudes GM* (q2), GE*(q2), and the resonant multipole ratio REM(q2)≡ E1+3/2(q2)/M 1+3/2(q2) is performed in terms of the well-known nucleon isovector Sachs form factor GMV. Our methods are fully relativistic with conservation of the electromagnetic current guaranteed. We find that GM *(q2) decreases more rapidly than the nucleon dipole form factor when -q2≳1 GeV2/c2 and that REM(q2) remains small even for very high four-momentum transfer implying that the perturbative QCD prediction REM(q2)→1 is purely asymptotic and is valid only for extremely high q2 . © 2004 Elsevier B.V.
