Description
Particle tracks from a proton-proton collision seen by the CMS (compact muon solenoid) detector at CERN (the European particle physics laboratory) near Geneva, Switzerland. Before the collision the ions had been accelerated by the large hadron collider (LHC). The central tracking chamber (cylindrical) and muon chambers (red rectangles) of the detector are seen end-on in outline. The collision produced a number of unidentified hadrons (orange) and a strange bottom meson. The strange bottom meson is not seen, but is revealed through its decay products; a pair of muons (red lines). The green lines show the energy deposited by the muons in the detector's muon chambers.
