dc.description.abstractA new formalism is presented for the calculation of the contribution [delta][varrho] to [varrho] = Mw2/Mz2cos2[theta]w from heavy particles transforming according to arbitrary representations of SU(2) x U(1). A conjecture for the necessary and sufficient conditions that [delta][varrho][ges]0 for all values of masses and mixing angles within a particular multiplet is formulated. A number of examples are given (all consistent with the conjecture) and the significance of improved knowledge of [varrho] vis a vis the possible existence of undiscovered heavy particles discussed.en_US
