摘要
该文利用SU(2)非阿贝尔规范对称性研究了强子气体中标量和矢量介子相互作用模型。通过Higgs机制让SU(2)规范对称性发生自发破缺,矢量介子场将获得质量,并且通过引入ξ规范条件,使得强子气体模型具有规范不变性。该模型不仅自然地包含了矢量、标量介子场、电磁场之间的相互作用,而且还包含了规范固定项和Faddeev-Popov鬼场等非阿贝尔规范场效应。
By using the SU(2)non-Abel gauge symmetry,the hadronic interaction model of scalar mesons and vector mesonsis discussed.After the SU(2)gauge symmetry shows spontaneous breaking induced by the Higgs mechanism,the vectormesons will obtain mass.The hadronic gas model satisfies the invariant of the gauge transformation due to theξgaugecondition.The hadronic gas model contains the interaction between scalar masons,vector mesons and electromagnetic field.Furthermore the non-Abel gauge field effects of gauge fixation and Faddeev-Popov ghost field are included in the model.
