ResumoThe main decay modes of the eta meson are discussed with emphasis on large symmetry breaking effects induced by the mass of the strange quark. It is argued that these SU3-breaking effects amount to corrections involving factors of 2 to 3 in rate in the above decay modes. This is in line with the well-known large correction factors in the nonleptonic decays KS →2π and D0→K+K−, π+π−.
