Description

600 events of rare electromagnetic decay eta→μ+μ-γ have been observed. Its respective probability has been measured BR(eta→μ+μ-γ)=(3.1+-0.4)x10-4. The eta-meson electromagnetic form factor has been determined: F(msub(μμ)sup(2); 0)=(1-msub(μμ)sup(2)/Λsup(2))sup(-1), where Λ=(0.72+-0.09) GeV/c2 is in good consistence with the vector meson dominance model
