Strangeness Now

Physicists observed that these "strange" particles were always produced in pairs through the strong interaction but decayed individually through the weak interaction. This led to the discovery of the , the fundamental piece of matter that carries this property. 1. Identify the Quark Composition

When developing a "piece" of a reaction (an equation), you must ensure that total strangeness is conserved in strong and electromagnetic interactions. strangeness

The strangeness of a particle is determined by the number of strange quarks ( ) and strange antiquarks ( like kaons and hyperons

The concept of ( ) in particle physics was developed to explain why certain subatomic particles, like kaons and hyperons, lived much longer than expected before decaying. strangeness
