) it contains. By convention, a strange quark has a strangeness value of , while an anti-strange quark has 2. Apply the Strangeness Formula
The strangeness of a particle is determined by the number of strange quarks ( ) and strange antiquarks ( strangeness
To calculate the total strangeness of a composite particle (like a baryon or meson), use the following sum: ) it contains
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. Identify the Quark Composition
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
