ATLAS and CMS: observing a new boson near 125 GeV

Contribution grade

Particle physics · Scoped scientific or research-capability contribution

Reference score170,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

The two experiments separately report signals of a new particle, central observations in the discovery of the Higgs boson.

Scientific scope

The two experiments separately report signals of a new particle, central observations in the discovery of the Higgs boson. Scope limitation: The 2012 discovery papers remain distinct from later spin, parity and coupling measurements. Experimental teams and theorists who proposed the Higgs mechanism receive separate attribution. Both independent experimental sources are retained.

Evidence

Assessment uses the catalogue-linked source evidence for the stated contribution. The 2012 discovery papers remain distinct from later spin, parity and coupling measurements. Experimental teams and theorists who proposed the Higgs mechanism receive separate attribution. Both independent experimental sources are retained.
