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…

The 7/11 rule: an estimate of m_rho/f_pi
M. Golterman, S. Peris
We derive an estimate for the ratio of the rho mass and the pion decay constant from an analysis of vector and axial-vector two-point functions using large-Nc, lowest-meson dominan…

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…
