A more general form of the Bethe Salpater wavefunction for a quark antiquark bound state, in accordance with the spirit of nonrelativistic approximation, is constructed, and the relativistic Salpeter equation is reduced to two 2×2 matrix equations under an instantaneous approximation, which includes not only the contributions comming from a positive energy state but also ones of a negative energy state, and has no anomalous solution.

作者： Wang Wenyu liu jueping(Department of Physics, Wuhan University, Wuhan 430072, China)

Using a new perturbative expansion method in Quantum Chromodynamics with a non-perturbative gluon background, the gluon propagator is calculated up to the one-loop level, and renormalized in the modified minimal subtraction scheme. The resultant renormalization constants of the quantum gluon field and the gauge parameter receive a non-perturbative contribution coming from the gluon condensate besides the usual perturbative one, respectively.

在量子色动力学(QCD)低能等效理论的框架中,利用瞬子媒质中的等效夸克传播子,在领头阶单圈水平上计算了与夸克-反夸克非局域张量流耦合的纵向光子光锥波函数hγ∥(u,P2)以及相应的耦合常数fγ∥(P2)的解析表达式,得到了包含扭度2和3贡献的光子光锥波函数hγ∥(u,P2)与夸克所分担的纵向动量份额u和光子虚度P2的关系,并考察了耦合常数fγ∥(P2)随P2的变化而变化的性状.结果表明,纵向波函数在不同虚度下都满足u1-u对称,而且相应的耦合常数与横向波函数的耦合常数在高能极限下趋于一致.

采用Gaussian求和规则计算Ds(0+)介子的质量.首先,通过Laplace变换得到了Ds(0+)介子流的两点函数以及谱函数的Gaussian变换;进而导出了关于Ds(0+)介子的质量与衰变常数的Gaussian求和规则;采用QCD标准的普适输入参数,得到了关于Ds(0+)介子质量与衰变常数的数值结果:mGauss=2.41±0.05±0.15 GeV和fGauss=0.30±0.02 GeV,所得的结果比Borel求和规则的结果(mBorel=2.48±0.03 GeV)要低,在理论计算误差范围内与Borel求和规则的结果相比更符合实验结果(mexp=2.317 6±0.001 3 GeV).
