Aspects of chiral pion-nucleon physics
V. Bernard, N. Kaiser, Ulf-G. Meißner
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 fr…
Effective Lagrangian approach to vector mesons, their structure and decays
F. Klingl, N. Kaiser, W. Weise
An improved update of the structure and decays of , and mesons based on a chiral SU(3) Lagrangian, including anomaly terms is presented. We demonstrate that a consiste…
Nucleon electroweak form factors: Analysis of their spectral functions
V. Bernard, N. Kaiser, Ulf-G. Meißner
We investigate the imaginary parts of the nucleon electromagnetic and axial form factors close to threshold in the framework of heavy baryon chiral perturbation theory. For the iso…
On the analysis of the pion--nucleon --term: The size of the remainder at the Cheng--Dashen point
V. Bernard, N. Kaiser, Ulf-G. Meißner
We calculate the one--loop contributions of order to the difference between the on--shell pion--nucleon scattering amplitude at the Cheng--Dashe…
Double neutral pion photoproduction at threshold
V. Bernard, N. Kaiser, Ulf-G. Meißner
We consider the chiral expansion of the threshold amplitude for the reaction to order . We substantiate a claim that this photoproduction channe…
Chiral corrections to the Kroll-Ruderman theorem
V. Bernard, N. Kaiser, Ulf-G. Meißner
We calculate the one--loop corrections to the Kroll--Ruderman low--energy theorems for charged pion photoproduction in the framework of heavy baryon chiral perturbation theory. We…
