چکیده
The negative-parity baryons are studied by a novel approach in the QCD sum rule. It is found that the parity of the ground-state nucleon is determined by the sign of the quark condensate. We predict the mass of negative-parity nucleon.

متن کاملSign convention of residues in QCD sum rules
where |N(q)〉 is a one-nucleon state with four-momentum q and u(q) is a Dirac spinor for the nucleon. λN is the coupling strength which measures the ability of the interpolating field ηN to excite the nucleon from the QCD vacuum. In fact, the above interpolating field couples to the negative parity nucleons also. Recently, the techniques to study negative parity baryons are given in Ref. and Ref...
متن کاملThe suppression of πNN(1535) coupling in QCD
The light cone QCD sum rules are employed to calculate the πNN(1535) coupling gπNN∗ . We study the two point correlation function of two nucleon currents sandwiched between the vacuum and the pion state. The contribution from the excited states and the continuum is subtracted cleanly through the double Borel transform with respect to the nucleon andN(1535) momenta, p1, p 2 2 = (p−q) . Our calcu...
متن کاملPenta-quark baryon from the QCD Sum Rule
Exotic penta-quark baryon with strangeness +1, Θ, is studied in the QCD sum rule approach. We derive sum rules for the positive and negative parity baryon states with J = 1 2 and I = 0. It is found that the standard values of the QCD condensates predict a negative parity Θ of mass ≃ 1.5 GeV, while no positive parity state is found. We stress the roles of chiral-odd condensates in determining th...
متن کاملSecond Class Current in QCD Sum Rules
Induced tensor charge of the nucleon gT , which originates from G-parity violation, is evaluated from QCD sum rules. We find that gT /gA with gA being the axial charge is −0.0152 ± 0.0053 which is proportional to u-d quark mass difference. This result is small compared to preliminary analysis of the experiment, but is consistent with the estimate in the MIT bag model. PACS numbers: 12.38.Lg, 14...
