First observation of omega-minus particle
This historic photograph from the 80-inch (200cm) bubble chamber at the Brookhaven National Laborat- ory shows the first observation of the omega-minus particle, which consists of three strange quarks. A negative kaon enters at bottom left & collides with a proton in the chamber's hydrogen to produce 3 particles, including the omega-minus. The omega travels a short distance before decaying into a negative pion, which veers to the right across the bottom part of the picture, & a neutral xi partic- le which leaves no track. Discovery of the omega in 1964 confirmed Gell-Mann & Ne'eman's classific- ation of subatomic particles, the 'Eightfold Way'.
