Chiral Symmetry of Nucleon Resonances in QCD sum rules
T. Nakamura, P. Gubler, M. Oka
The QCD sum rule approach is employed in order to study chiral properties of positive- and negative-parity nucleon resonances. It is pointed out that nucleons with an ``exotic'' ch…

Mixings of 4-quark components in light non-singlet scalar mesons in QCD sum rules
J. Sugiyama, T. Nakamura, N. Ishii +2
Mixings of 4-quark components in the non-singlet scalar mesons are studied in the QCD sum rules. We propose a formulation to evaluate the cross correlators of q\bar q and qq\bar q…
