New nonrenormalization theorems for anomalous three point functions
Marc Knecht, Santiago Peris, Michel Perrottet +1
Nonrenormalization theorems involving the transverse, i.e. non anomalous, part of the <VVA> correlator in perturbative QCD are proven. Some of their consequences and questions they…
Hadronic light-by-light scattering contribution to the muon g-2: an effective field theory approach
M. Knecht, A. Nyffeler, M. Perrottet +1
The hadronic light-by-light contribution to a_{mu}, the anomalous magnetic moment of the muon, is discussed from the point of view of an effective low-energy theory. As an applicat…
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…
Matching Long and Short Distances in Large-Nc QCD
S. Peris, M. Perrottet, E. de Rafael
It is shown, with the example of the experimentally known Adler function, that there is no matching in the intermediate region between the two asymptotic regimes described by pertu…
