Abstract: A phenomenological analysis of various decay processes is performed in order to test the large Nc 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.
