Weak hyperon decays in heavy baryon chiral perturbation theory: Renormalization and applications
B. Borasoy, G. Muller
The complete renormalization of the weak Lagrangian to chiral order q^2 in heavy baryon chiral perturbation theory is performed using heat kernel techniques. The results are compar…

Virtual photons in SU(2) chiral perturbation theory and electromagnetic corrections to scattering
Ulf-G. Meißner, G. Müller, S. Steininger
We construct the generating functional of two flavor chiral perturbation theory including the effects of virtual photons in the one loop approximation. As an application, we calcul…
