The mass limits shown below apply to a Higgs boson ${{\mathit H}^{0}}$ with Standard Model couplings whose mass is a priori unknown. These mass limits are compatible with and independent of the observed signal at about 125 GeV. In particular, the symbol ${{\mathit H}^{0}}$ employed below does not in general refer to the observed signal at about 125 GeV.

The cross section times branching ratio limits quoted in the footnotes below are typically given relative to those of a Standard Model Higgs boson of the relevant mass. These limits can be reinterpreted in terms of more general models (e.g.$~$extended Higgs sectors) in which the Higgs couplings to ${{\mathit W}}$, ${{\mathit Z}}$ and fermions are re-scaled from their Standard Model values.

All data that have been superseded by newer results are marked as “not used” or have been removed from this compilation, and are documented in previous editions of this $\mathit Review$ of Particle Physics.
