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 equals open paren number of s bar quarks close paren minus open paren number of s quarks close paren 3. Check for Conservation strangeness
To calculate the total strangeness of a composite particle (like a baryon or meson), use the following sum: The strangeness of a particle is determined by
When developing a "piece" of a reaction (an equation), you must ensure that total strangeness is conserved in strong and electromagnetic interactions. strangeness
