This page delivers no verdict; it presents claims and evidence with their sources. No theory in science is absolute. Method

For everyone

The Higgs boson, predicted in 1964, was announced on 4 July 2012 by the ATLAS and CMS experiments at CERN's Large Hadron Collider. The particle is the signature of the Higgs field, which is thought to give elementary particles their mass.

For specialists

Both experiments observed an excess at a mass of about 125 GeV in the H → γγ and H → ZZ* → 4ℓ channels, with a combined significance of about 5σ. Later measurements showed spin zero and positive parity, and couplings to fermions and bosons proportional to mass. The Higgs self-coupling has not yet been measured directly.

Measurement

Two independent detectors found significant excesses at the same mass with independent analyses.[1][2]
