Abstract We present general formulas for the oblique-correction parameters S, T, U, V, W, and X in a model of New Physics having arbitrary numbers of scalar leptoquarks of the five permissible types. We allow for a general mixing among the scalars of the various electric charges, viz. −4/3, −1/3, 2/3, and 5/3. We then extend the formulas to the case of a New Physics model with additional scalars in any representations of the gauge group SU(2) × U(1), mixing arbitrarily among themselves.
