Predictions of masses for light hybrid baryons
Qi-Nan Wang, Ding-Kun Lian, Wei Chen +4
Within the method of parity-projected QCD sum rules, we study the mass spectra of light hybrid baryons with $I(J^{P})=1/2(1/2^{\pm}), 3/2(1/2^{\pm}), 1/2(3/2^{\pm}), 3/2(3/2^{\pm})…
Strengthening the Bridge Between Chiral Lagrangians and QCD Sum-Rules
J. Ho, Amir H. Fariborz, T. G. Steele
Previous work has shown that mesonic fields in chiral Lagrangians can be systematically connected to quark-level operators in QCD sum rules through chiral-symmetry constrained and…
Light hybrid baryons in QCD sum rules
Wei Chen, Qi-Nan Wang, Ding-Kun Lian +4
We have calculated the mass spectra of nucleon and delta hybrid baryons with both positive-parity and negative-parity by using the method of QCD sum rules. We predicte that the low…
Charmonium-like states with the exotic quantum number
Hong-Zhou Xi, Hua-Xing Chen, Wei Chen +3
We apply the method of QCD sum rules to study the tetraquark states with the exotic quantum number , and extract the mass of the lowest-lying s…
