ON THE MAGNETIC MOMENT OF W± BOSONS IN WEINBERG-SALAM MODEL

  • We discuss the magnetic moment of W± bosons in W-S model. First we assume that there is no spontaneous symmetry broking. starting from the formalism of path integrals and using the gauge invariance requirement, we obtain the Ward-Takahashi identities for the 3-line VIB proper vertex functions and prove that its tensor structure is the same form as that of bare vertex couplings, which indicated the W± bosons have neither anomalous magnetic moment nor electric quadrupole moment. For the realistic case of spontaneous symmetry breaking, we introduce in the Lagrangian an explicit symmetry breaking term. After discussing the problem of analytic continuation for mass of W± bosons, we prove that prove that the above mentioned conclusion is still valid here.

ON THE MAGNETIC MOMENT OF W± BOSONS IN WEINBERG-SALAM MODEL

    Corresponding author: PENG Hong-An,

Abstract: We discuss the magnetic moment of W± bosons in W-S model. First we assume that there is no spontaneous symmetry broking. starting from the formalism of path integrals and using the gauge invariance requirement, we obtain the Ward-Takahashi identities for the 3-line VIB proper vertex functions and prove that its tensor structure is the same form as that of bare vertex couplings, which indicated the W± bosons have neither anomalous magnetic moment nor electric quadrupole moment. For the realistic case of spontaneous symmetry breaking, we introduce in the Lagrangian an explicit symmetry breaking term. After discussing the problem of analytic continuation for mass of W± bosons, we prove that prove that the above mentioned conclusion is still valid here.
