1^(-+)Hybrid Meson and QCD Sum Rules

碩士 === 中原大學 === 應用物理研究所 === 93 === We use the QCD sum rules approach to investigate the mass of the $J^{PC}=1^{-+}$ hybrid meson. After calculating the current-current correlator of the hybrid current $J_mu =overline{q}gamma_ u igG_{mu u}t^aq$, and using OPE expansion, we obtain the spectral functio...
