The properties of the elusive scalar of the standard model, given its mass, are entirely specified. In spite of this, there are good reasons to re-discuss some obvious questions:

• To what extent does a given set of observations compatible with the predictions constitute an indisputable discovery?
• What process and analysis procedure can reach 'discovery level' first?
• With what confidence can one determine the quantum numbers of a putative scalar, and study whether it is elementary or composite, and pure or 'impure' in its couplings?
• How and how well can one favour or exclude 'Higgs impostors'?

Our emphasis is on the 'most wanted' standard particle and its ZZ or ZZ^* decays. Yet, our analysis of the Higgs and its possible impostors encompasses the study and characterization of novel neutral bosons of spin 1 and 2 and is extensible to other particles and decays.
