英文摘要The BES-III Collaboration recently reported the observation of anomalously large isospin violations in J/psi --> gamma eta(1405/1475) --> gamma pi(0)f(0)(980) --> gamma + 3 pi, where the f(0)(980) in the pi pi invariant mass spectrum appears to be much narrower (similar to 10 MeV) than the peak width (similar to 50 MeV) measured in other processes. We show that a mechanism, named as triangle singularity (TS), can produce a narrow enhancement between the charged and neutral K (K) over bar thresholds, i.e., 2m(K+) similar to 2m(K0). It can also lead to different invariant mass spectra for eta(1405/1475) --> a(0)(980)pi and K (K) over bar* + c.c:, which can possibly explain the long-standing puzzle about the need for two close states eta(1405) and eta(1475) in eta pi pi and K (K) over bar pi, respectively. The TS could be a key to our understanding of the nature of eta(1405/1475) and advance our knowledge about the mixing between a(0)(980) and f(0)(980).
