Abstract: (APS)

Four-body decay of the Z0 into one heavy fermion (Mh≥50 GeV) and three light fermions has been calculated at O(αW3) in the SU(2)L×U(1) theory. The expression for the decay rate was derived and numerical integration over the phase space was performed. The heavy fermion was taken to be the top quark or any of the hypothetical fourth-generation quarks and leptons. For heavy-fermion mass Mh
