Experiments with -meson decays

Recent results and future prospects of particle physics experiments with neutral and charged K -meson (kaon) decays are reviewed. Topics include CP violation, rare decays, leptons in kaon decays, tests of CPT and quantum mechanics, radiative decays, hadrons in kaon decays, basic observables, V u s and CKM unitarity, and exotic searches. Experimental techniques developed for the kaon decay experiments are discussed.
