摘要：

The isovector axial vector form factors of N -> Delta transition are calculated by employing Light-cone QCD sum rules. The analytical results are analyzedby both the conventional method, and also by a Monte Carlo based approach which allows one to scan all of the parameter space. The predictions are also compared with the results in the literature, where available. Although the MonteCarlo analysis predicts large uncertainties in the predicted results, the predictions obtained by the conventional analysis are in good agreement with other results in the literature.
