Evidence of isospin-symmetry violation in high-energy collisions of atomic nuclei

Abstract Strong interactions preserve an approximate isospin symmetry between up (u) and down (d) quarks, part of the more general flavor symmetry. In the case of K meson production, if this isospin symmetry were exact, it would result in equal numbers of charged (K + and K −) and neutral (K 0 and $...
