Ground-state energy of pionic hydrogen to one loop
J. Gasser, M. A. Ivanov, E. Lipartia +2
We investigate the ground-state energy of the pi- p atom (pionic hydrogen) in the framework of QCD+QED. In particular, we evaluate the strong energy-level shift. We perform the cal…
The chiral effective pion-nucleon Lagrangian of order p^4
Nadia Fettes, Ulf-G. Meißner, Martin Mojzis +1
We construct the minimal effective chiral pion-nucleon SU(2) Lagrangian at fourth order in the chiral expansion. The Lagrangian contains 118 in principle measurable terms. We devel…
Reordering of Baryon Chiral Perturbation Theory
Martin Mojzis, Joachim Kambor
Reordering of the chiral perturbation series, proposed recently by Becher and Leutwyler in the framework of SU(2) baryonic ChPT, is applied to the SU(3) case. This results in impro…
Field Redefinitions and Wave Function Renormalization to in Heavy Baryon Chiral Perturbation Theory
Joachim Kambor, Martin Mojzis
Mass- and wave-function renormalization is calculated to order in heavy baryon chiral perturbation theory. Two different schemes used in the literature are considered. Severa…
Working group on and N interactions - Summary
Ulf-G. Meißner, Martin Sevior, A. Badertscher +16
This is the summary of the working group on and N interactions of the Chiral Dynamics Workshop in Mainz, September 1-5, 1997. Each talk is represented by an extended one pa…
Wave function renormalization in heavy baryon chiral perturbation theory
G. Ecker, M. Mojzis
We establish exact relations between relativistic form factors and amplitudes for single-baryon processes and the corresponding quantities calculated in the framework of heavy bary…
Elastic pion-nucleon Scattering to O(p^3) in Heavy Baryon Chiral Perturbation Theory
Martin Mojzis
The elastic pi-N scattering amplitude in the isospin limit is calculated in the framework of heavy baryon chiral perturbation theory, up to the third order. Threshold parameters li…
Low-energy expansion of the pion-nucleon Lagrangian
Gerhard Ecker, Martin Mojzis
The renormalized pion-nucleon Lagrangian is calculated to O(p^3) in heavy baryon chiral perturbation theory. By suitably chosen transformations of the nucleon field, the Lagrangian…
