rho parameter in supersymmetric models

Journal Article · · Phys. Rev. D; (United States)
; ;
The electroweak rho parameter is examined in a general class of supersymmetric models. Formulas are given for one-loop contributions to ..delta..rho from scalar quarks and leptons, gauge and Higgs fermions, and an extra doublet of Higgs scalars. Mass differences between members of isodoublet scalar quarks and leptons are constrained to be less than about 200 GeV.
