Question

Quizplus · Accepted Answer

The strangeness of an anti-proton is 0 because strangeness is a quantum number that describes the presence of strange quarks in a particle. An anti-proton, being the antiparticle of a proton, is composed of antiquarks, specifically two up antiquarks and one down antiquark, none of which are strange quarks. Therefore, its strangeness is 0.
