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 chambers 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 emans classific- ation of subatomic particles, the Eightfold Way

EDITORS COMMENTS
This historic photograph captures a groundbreaking moment in the field of particle physics. Taken by the 80-inch (200cm) bubble chamber at the Brookhaven National Laboratory, it showcases the first observation of the omega-minus particle. This elusive particle, composed of three strange quarks, had long been hypothesized but never directly observed until this momentous event. In the image, we witness a negative kaon entering from the bottom left corner and colliding with a proton within the hydrogen-filled chamber. The collision produces three particles, including the omega-minus. The omega travels only a short distance before decaying into a negative pion that swiftly veers to the right across the lower part of the picture. Simultaneously, a neutral xi particle is emitted without leaving any trace behind. The discovery of this omega-minus particle in 1964 confirmed Murray Gell-Mann and Yuval Ne'eman's classification system known as "the Eightfold Way". Their theory provided an organized framework for understanding subatomic particles based on their properties and behaviors. This magnified monochrome image not only captures scientific history but also represents progress in our comprehension of fundamental building blocks that make up our universe. It serves as a testament to human curiosity and ingenuity in unraveling nature's mysteries through high-energy physics research conducted at esteemed institutions like Brookhaven National Laboratory.
