Higgs boson - Wikipedia
WEBThe most likely possibility is for the Higgs to decay into a pair of W bosons (the light blue line in the plot), which happens about 21.5% of the time for a Higgs boson with a mass of 125 GeV/c2. [2] The W bosons can subsequently decay either into a quark and an antiquark or into a charged lepton and a neutrino.
The Higgs boson - CERN
WEBThe Higgs boson can't be “discovered” by finding it somewhere but has to be created in a particle collision. Once created, it transforms – or “decays” – into other particles that can be detected in particle detectors. Physicists look for traces of these particles in data collected by the detectors.

WEBApr 10, 2024 · The new scalar (spin 0) boson was observed at the time mainly in two rare decay channels offering the cleanest signal, the decay in a pair of photons, which involved a purely quantum virtual...
The Higgs boson: a landmark discovery - ATLAS Experiment at …
WEBThe discovery of the Higgs boson relied on measurements of its decay to vector bosons: the photon, W and Z. The existence of such interactions provided crucial evidence for a process known as spontaneous electroweak symmetry breaking to have occurred in our Universe, and is a key prediction of the theory of the BEH mechanism.
