<hadron>[Hadronic] processes with disconnected quark-flavour lines are often suppressed relative to connected <quark> rearrangement. A predominantly strange <phi meson> can decay to <kaons> through light-pair creation while its original strange lines survive, whereas a purely pionic final state requires strange-pair annihilation. The rule is an approximate dynamical pattern, not an exact conservation law.
