Kaon-Nucleon scattering lengths from the experiments on kaonic hydrogen and kaonic deuterium
Akaki Rusetsky
Within the framework of a low-energy effective field theory we consider the procedure of extraction of the S-wave kaon-nucleon scattering lengths a0 and a1 from a combined fit to t…
Axial, induced pseudoscalar, and pion-nucleon form factors in manifestly Lorentz-invariant chiral perturbation theory
M. R. Schindler, T. Fuchs, J. Gegelia +1
We calculate the nucleon form factors G_A and G_P of the isovector axial-vector current and the pion-nucleon form factor G_piN in manifestly Lorentz-invariant baryon chiral perturb…
NN scattering in higher derivative formulation of baryon chiral perturbation theory
D. Djukanovic, J. Gegelia, S. Scherer +1
We consider a new approach to the nucleon-nucleon scattering problem in the framework of the higher-derivative formulation of baryon chiral perturbation theory. Starting with a Lor…
Kinematic Rotations of N-particle Hyperspherical Basis
Lia Leon Chachanidze-Margolin, Shalva Tsiklauri
The kinematical rotations of N-partical Hyperspherical basis are considered. The recurrence relation method of determination of transformation coefficients for arbitrary N-values i…
Kaon-nucleon scattering lengths from kaonic deuterium experiments
Ulf-G. Meißner, Udit Raha, Akaki Rusetsky
The extraction of the S-wave kaon-nucleon scattering lengths a0 and a1 from a combined analysis of existing kaonic hydrogen and synthetic deuterium data has been carried out within…
