Nullification of multi-Higgs threshold amplitudes in the Standard Model
E. N. Argyres, R. Kleiss, C. G. Papadopoulos
Abstract
We show that nullification of all tree-order threshold amplitudes involving Higgs particles in the Standard Model occurs, provided that certain equations relating the masses of all existing elementary particles to the mass of the Higgs scalar are satisfied. The possible role of these relations in restoring the high-multiplicity unitarity and their phenomenological relevance are briefly discussed.
