Strictly Analytic Calculation to the Renormalized Finite Quantity with Z_0 Loop Propagator

摘要

In the electroweak standard model, in consideration of the interaction between fermion fields and gauge fields, the authors analyze normal method (Feynman high-dimensional convergence integral method), which separate the finite of Z loop propagator firstly, find a new method-great momentum integral limitation method. Using this method, the authors obtain an analytic expression of one-dimensional integral.
