On the size of isospin violation in low-energy pion-nucleon scattering
Nadia Fettes, Ulf-G. Meißner, Sven Steininger
We present an analysis of isospin-breaking effects in threshold pion-nucleon scattering due to the light quark mass difference and the dominant virtual photon effects. We discuss t…
Strange Magnetism
Thomas R. Hemmert, Ulf-G. Meissner, Sven Steininger
We present an analytic and parameter-free expression for the momentum dependence of the strange magnetic form factor of the nucleon and its corresponding radius which has been deri…
Renormalization of the chiral pion-nucleon Lagrangian beyond next-to-leading order
Ulf-G. Meißner, Guido Müller, Sven Steininger
The complete renormalization of the generating functional for Green functions of quark currents between one-nucleon states in two flavor heavy baryon chiral perturbation theory is…
On wave function renormalization and related aspects in heavy fermion effective field theories
Sven Steininger, Ulf-G. Meißner, Nadia Fettes
We reconsider the question of wave function renormalization in heavy fermion effective field theories. In particular, we work out a simple and efficient scheme to define the wave f…
Strange magnetism in the nucleon
T. R. Hemmert, Ulf-G. Meißner, S. Steininger
Using heavy baryon chiral perturbation theory to one loop, we derive an analytic and parameter-free expression for the momentum dependence of the strange magnetic form factor of th…
Pion-nucleon scattering in chiral perturbation theory I: Isospin-symmetric case
Nadia Fettes, Ulf-G. Meißner, Sven Steininger
We construct the complete effective chiral pion-nucleon Lagrangian to third order in small momenta based on relativistic chiral perturbation theory. We then perform the so-called h…
