摘要
以包含费米场与Higgs场且同时存在引力作用和内部基本相互作用的物理体系为对象,对拉氏量作了推广,并使其满足(ε ̄(mn),ξ ̄μ,ε ̄α)变换不变性;导出了在这种变换不变性下拉氏函数的特征形式,并研究了各类场之间可能存在的耦合。
A physical system comprising both fermion field and Higgs field and having both space-timegauge symmetry and internal gauge symmetry is studied; their Lagrangians are extended and letto satisfy the invariances under(ε ̄(mn),ξ ̄μ,ε ̄α)transformations; by these invariances thecharacteristic functional forms of the Lagrangians are derived; the possible couplings betweenfields are considered.
