Decays of 1/2^- Baryons in Chiral Effective Theory
Y. Nemoto, D. Jido, M. Oka +1
We construct an symmetric chiral effective model which includes parity pair baryon fields. It is assumed that the positive and negative parity baryons in t…
Suppression of PiNN* Coupling and Chiral Symmetry
D. Jido, M. Oka, A. Hosaka
Meson-baryon couplings between positive and negative parity baryons are investigated using two point correlation functions in the soft meson limit. We find that the pi NN^* couplin…
Negative Parity Baryons in the QCD Sum Rule
M. Oka, D. Jido, A. Hosaka
Masses and couplings of the negative parity excited baryons are studied in the QCD sum rule. Separation of the negative-parity spectrum is proposed and is applied to the flavor oct…
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…
