Natural relations and Appelquist-Carazzone decoupling theorem

Journal Article · · Phys. Rev. D; (United States)
; ;
It is pointed out that in some cases violation of the Appelquist-Carazzone decoupling theorem in spontaneously broken gauge theories is related to the presence in such theories of the so-called natural zeroth-order relations. In this context heavy-fermion effects in the Glashow-Salam-Weinberg model are discussed.
