Radiative corrections to K_{l3} decays
V. Cirigliano, M. Knecht, H. Neufeld +2
We present a complete calculation of the K_{l3} decays K^+ --> pi^0 l^+ nu_l and K^0 --> pi^- l^+ nu_l to O(p^4, (m_d-m_u) p^2, e^2 p^2) in chiral perturbation theory with virtual…

Chiral Perturbation Theory with Virtual Photons and Leptons
M. Knecht, H. Neufeld, H. Rupertsberger +1
We construct a low-energy effective field theory which allows the full treatment of isospin-breaking effects in semileptonic weak interactions. To this end, we enlarge the particle…

The Electromagnetic Interaction in Chiral Perturbation Theory
H. Neufeld, H. Rupertsberger
We investigate electromagnetic effects in the framework of chiral perturbation theory. Using a completely independent method, we confirm Urech's results for the divergences of the…
