Using the zero-width approximation, the mass of the 1 - vector odd-glueball is then estimated in the framework of QCD sum rules. Our result agrees with the prediction from the calculation of the lattice gauge theory. 量子色动力学 求和规则 矢胶怪球 quantum chromodynamics QCD sum rules vector odd-glueball O572.3 国家自然科学基金(61672102) 1996-01-01 2021-04-01 1
