Chiral expansion of the nucleon mass to order q^6
M. R. Schindler, D. Djukanovic, J. Gegelia +1
We present the results of a complete two-loop calculation at order q^6 of the nucleon mass in manifestly Lorentz-invariant chiral perturbation theory. The renormalization is perfor…
Nucleon Form Factors of the Isovector Axial-Vector Current: Situation of Experiments and Theory
M. R. Schindler, S. Scherer
The theoretical and experimental status of the isovector axial-vector current form factors G_A(q^2) and G_P(q^2) of the nucleon is reviewed. We also describe a new calculation of t…
Probing the convergence of perturbative series in baryon chiral perturbation theory
D. Djukanovic, J. Gegelia, S. Scherer
Using the examples of pion-nucleon scattering and the nucleon mass we analyze the convergence of perturbative series in the framework of baryon chiral perturbation theory. For both…
Magnetic dipole moment of the in chiral perturbation theory
C. Hacker, N. Wies, J. Gegelia +1
The magnetic dipole moment of the is calculated in the framework of manifestly Lorentz-invariant baryon chiral perturbation theory in combination with the extended on-mas…
Consistency of the interaction in chiral perturbation theory
N. Wies, J. Gegelia, S. Scherer
We analyze the constraint structure of a spin-3/2 particle interacting with a pseudoscalar. Requiring the self consistency of the considered effective field theory imposes restrict…
