N→Δ A transition amplitudes from QCD sum rules.

We present a calculation of the N to Δ electromagnetic transition amplitudes using the method of QCD sum rules. A complete set of QCD sum rules is derived for the entire family of transitions from the baryon octet to decuplet. They are analyzed in conjunction with the corresponding mass sum rules using a Monte-Carlo-based analysis procedure. Valid sum rules are identified and their predictions are obtained. The results are compared with experiment and other calculations. [ABSTRACT FROM AUTHOR]
