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