Higher-order effects in Fermi-type charged current theory of weak interactions: Semi-leptonic neutral currents

Research output: Contribution to journal › Article › peer-review

Abstract

In a convergent field theory rescattering graphs lead to neutral-current effects of the observed magnitude if the effective cut-off momentum is ∼G^{- 1 2} ≈ 300 GeV. A perturbation expansion is justified owing to the value f=0.18 of the resulting expansion parameter.
