Hard exclusive electroproduction of decuplet baryons in the large N-c limit

The cross sections and transverse spin asymmetries in the hard exclusive el ectroproduction of decuplet baryons are calculated in the large N-c limit a nd found to be comparable to that of octet baryons. Large N-c selection rul es for the production amplitudes are derived, leading to new sensitive test s of the spin aspects of the QCD chiral dynamics both in the nonstrange and strange sectors. Importance of such studies fur the reliable extraction of the: pion form factor from pion electroproduction is explained.
