In the “golden channel,” this particle decays into two Z bosons, which each decay into two leptons. The fact that the mass of this particle is significantly lower than the Planck (“plonk”) mass is one manifestation of the hierarchy problem. This particle’s potential takes on a Mexican hat shape, a consequence of its potential’s vacuum expectation value being nonzero. After electroweak symmetry breaking, this particle’s namesake field couples to the (10[1])W and Z bosons (10[1])to give them mass. (10[1])The ATLAS and CMS experiments at CERN discovered this particle in 2012. (10[1])For 10 points, name this particle, the last predicted by the Standard Model to be discovered, named for a British physicist. (10[1])■END■ (10[1])
