Phenomenological test of the large N_c ChPT predictions for the pseudoscalar mixing parameters

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

A phenomenological analysis of various decay processes is performed in order to test the large NcN_c Chiral Perturbation Theory predictions for the octet and singlet pseudoscalar decay constants and mixing angles. The results obtained hint at a disagreement with the expectations of this theoretical framework although the statistical significance is still limited.
