Caption: Bubble chamber photo of the production & decay of a lambda particle. A high-energy proton enters at bottom, knocks out an atomic electron (the faint spiral) in passing, then collides with a proton at rest in the liquid hydrogen of the bubble chamber. The collision produces 7 negative pions which curve left, 9 positive particles which curve right (including a proton & a kaon as well as 7 positive pions), and the lambda. Being neutral, the lambda leaves no track, but reveals its existence when it decays into a proton & a negative pion at upper centre. The lambda is one of the family of strange particles, which contain a strange quark.
