ALEPH experiment: Candidate of Higgs boson production(CERN)

Computer reconstruction of a "golden event" in the BABAR Detector
An electron and positron have annihilated at the center of the vertex detector (orange) in this cross-sectional view, producing a B and an anti-B meson. One of them decays into a pair of muons and a pair of pions (gold tracks), while the other (the "tagging" B) decays into a kaon and three pions. (SLAC)

Simulation of a Higgs decay to four isolated muons in the CMS detector at the Large Hadron Collider at CERN. The lines denote particles produced from the collision of a pair of ultra-high energy protons. Energy deposits of the particles in the detector are shown in blue.(CERN)
