The pionic beta decay in chiral perturbation theory
V. Cirigliano, M. Knecht, H. Neufeld +1
Within the framework of chiral perturbation theory with virtual photons and leptons, we present an updated analysis of the pionic beta decay including all electromagnetic contribut…

Electroweak Hadronic Contributions to the muon g-2
M. Knecht, S. Peris, M. Perrottet +1
We reanalyze the two-loop electroweak hadronic contributions to the muon g-2 that may be enhanced by large logarithms. The present evaluation is improved over those already existin…

Electromagnetic Corrections to Charged Pion Scattering at Low Energies
M. Knecht, A. Nehme
The electromagnetic corrections to the low energy scattering amplitude involving charged pions only are investigated at leading and next-to-leading orders in the two-flavour chiral…
