A New Approach to Weak Amplitudes in Large-Nc QCD

M. Knecht, S. Peris, E. de Rafael +1

We report on some recent progress made in understanding weak matrix elements of mesons in the context of the next-to-leading order of the large-Nc approximation to QCD. Specificall…

Large-Nc QCD and Weak Matrix Elements

E. de Rafael

I report on recent progress in calculating electroweak processes within the framework of QCD in the 1/Nc expansion.

Decay of pseudoscalars into lepton pairs and large-Nc QCD

M. Knecht, S. Peris, M. Perrottet +2

The counterterm combination that describes the decay of pseudoscalar mesons into charged lepton pairs at lowest order in chiral perturbation theory is considered within the framewo…
