摘　　要：首先把不包含Higgs场的六维算符用物理场来表示,然后写出带电和不带电的三重波色子WWV和ZZV的有效拉氏量。最后,推导出有效拉氏量所对应的费曼规则。First we write the dimension six operators without Higgs particle in terms of physical gaugeboson fields. Then we provide the effective Lagrangian for the charged and neutral triple gauge-boson WWγ, WWZ and ZZγ, ZZZ couplings. Note that neutral gauge boson couplings are not present in standard model. Finally we derive the Feynman rules for effective Lagrangian.
