由QCD求和规则计算s夸克质量

Determining Strange Quark Mass from QCD Sum Rule

简要回顾了量子色动力学求和规则在计算s夸克质量方面的应用。结合Dominguez,Gend和Paver的工作,重新考虑渐近自由阈以下的谱函数后,计算了s夸克的质量,得到s夸克的跑动质量-ms(1 GeV)=219 MeV。讨论了影响计算结果精度的可能因素。

We gave a brief review on the determination of the strange quark mass by QCD sum rule.Combining with the work of Dominguez,Gend and Paver,we reconstructed the spectral function below the threshold by the sum of two Breit-Wigner form resonances,we obtained s（1 GeV）=219 MeV,where s is the running mass of the strange quark.
