The Oblique Corrections from Heavy Scalars in Irreducible Representations
Hong-Hao Zhang, Wen-Bin Yan, Xue-Song Li
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.
