Strangeness Online

S=(number of s̄ quarks)−(number of s quarks)cap S equals open paren number of s bar quarks close paren minus open paren number of s quarks close paren 3. Check for Conservation

To calculate the total strangeness of a composite particle (like a baryon or meson), use the following sum: strangeness

The strangeness of a particle is determined by the number of strange quarks ( ) and strange antiquarks ( S=(number of s̄ quarks)−(number of s quarks)cap S

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 Apply the Strangeness Formula

) it contains. By convention, a strange quark has a strangeness value of , while an anti-strange quark has 2. Apply the Strangeness Formula
