Heterotic Approach to the Nucleon Distribution Amplitude
arXiv:hep-ph/9403209 · doi:10.1016/0370-2693(94)90090-6
Abstract
We give an in-depth analysis of the determination procedure of the recently proposed heterotic nucleon distribution amplitude which hybridizes the best features of the Chernyak-Ogloblin-Zhitnitsky and the Gari-Stefanis models. With respect to the QCD sum-rule constraints, optimized versions of these amplitudes are derived in terms of which a "hybridity" angle can be introduced to systematically classify all models.
