Abstract
The Higgs particle is one of the cornerstones of the Standard Model of particle physics. Yet, we are not sure whether this particle is truly elementary or, on the contrary, is a composite state, the lightest resonance in a strongly interacting extended electroweak symmetry breaking sector perhaps. In this case, other resonances with various quantum numbers must exist and indeed they are predicted when requirements of unitarization and causality are demanded on this extended sector. In this work we propose to consider various possible alternatives for the Higgs and investigate proposal to experimentally reveal whether these alternatives may be the one chosen by Nature.
