Author(s): N. N. Achasov, A. A. Kozhevnikov, and G. N. Shestakov There are attempts in the literature to theoretically explain the large breaking of isotopic invariance in the decay η ( 1405 ) → f 0 ( 980 ) π 0 → 3 π by the mechanism containing the logarithmic (triangle) singularity, i.e., as being due to the transition η ( 1405 ) → ( K * K ¯ + K ¯ * K ) → ( K + K − + K 0 K ¯ 0 ) π 0 → f 0 ( 980 ) π 0 → 3 π .
