Regulariztion dependence of S=0 and S=-1 meson-baryon system in the chiral unitary model
S. I. Nam, H. -Ch. KIm, T. Hyodo +2
We investigate the dependence of s-wave meson-baryon scattering amplitudes on different regularizations within the framework of the chiral unitary model. We employ two different re…

Suppression of PiNN(1535) Coupling in the QCD Sum Rule
A. Hosaka, D. Jido, M. Oka
The πNN^* and ηNN^* coupling constants are studied in the QCD sum rule ($N^* \equiv N(1535)). We investigate the two point functions between the vacuum and a one meson state in the…
