A LARGE N STANDARD MODEL

An extension of the standard model, where the usual scalar doublet is replaced by a dimension 2N + 1 multiplet, is studied in the limit of l arge N. We determine the physical mass of the Higgs and the S, T and U parameters to leading order in this limit. We also consider the scatt ering of scalar particles and argue that it leads to an attractive int eraction between scalars whose charge difference is O(N).
