The Oblique Corrections from Heavy Scalars in Irreducible Representations
Abstract
The contributions to S, T and U from heavy scalars in any irreducible representation of the electroweak gauge group SU(2)L × U(1)Y are obtained. We find that in the case of a heavy scalar doublet, there is a slight difference between the S parameter we have obtained and that in previous works.
