The chiral effective pion – nucleon Lagrangian of order p

چکیده
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 develop both the relativistic as well as the heavy baryon formulation of the effective field theory. For the latter, we also work out explicitly all 1/m corrections at fourth order. We display all relevant relations needed to find the linearly independent terms. Work supported in part by Deutsche Forschungsgemeinschaft, contract Nos. Me 864/11-1 and Schu 439/10-1, and by VEGA grant No. 1/4301/97.

The chiral effective pion – nucleon Lagrangian of order p 4 # 1
We construct the minimal effective chiral pion–nucleon SU(2) Lagrangian at fourth order in the chiral expansion. The Lagrangian contains 114 in principle measurable and 4 contact terms needed for the renormalization. We develop both the relativistic as well as the heavy baryon formulation of the effective field theory. For the latter, we also work out explicitly all 1/m corrections at fourth or...
متن کاملThree-body Interactions among Nucleons and Pions
A chiral invariant effective Lagrangian may be used to calculate the three-body interactions among low-energy pions and nucleons in terms of known parameters. This method is illustrated by the calculation of the pion-nucleus scattering length. Research supported in part by the Robert A. Welch Foundation and NSF Grant PHY 9009850. Recent articles have described a systematic effective Lagrangian ...
متن کاملChiral Perturbation Theory
After a general introduction to the structure of effective field theories, the main ingredients of chiral perturbation theory are reviewed. Applications include the light quark mass ratios and pion–pion scattering to two–loop accuracy. In the pion–nucleon system, the linear σ model is contrasted with chiral perturbation theory. The heavy–nucleon expansion is used to construct the effective pion...
متن کاملPhoton- and pion-nucleon interactions in a unitary and causal effective theory
In recent years photonand pion-nucleon interactions have been successfully used as a quantitative challenge of chiral perturbation theory (χPT), which is a systematic tool to learn about low-energy QCD dynamics [1]. The application of χPT is however limited to the near threshold region. A method to extrapolate χPT results beyond the threshold region using analyticity and unitarity constraints w...
متن کاملDetermination of the low – energy constants of the next – to – leading order chiral pion – nucleon Lagrangian
The next–to–leading order chiral pion–nucleon Lagrangian contains seven finite low– energy constants. Two can be fixed from the nucleon anomalous magnetic moments and another one from the quark mass contribution to the neutron–proton mass splitting. We find a set of nine observables, which to one loop order do only depend on the remaining four dimension two couplings. These are then determined ...
