| dc.description | We further discuss possible sgoldstino interpretation of the observation, reported by the HyperCP collaboration, of three Σ^+\to pμ^+μ^- decay events with dimuon invariant mass 214.3 MeV within detector resolution. With sgoldstino mass equal to 214.3 MeV, this interpretation can be verified at existing and future B- and ϕ-factories. We find that the most natural values of the branching ratios of two-body B- and D-meson decays to sgoldstino P and vector meson V are about 10^{-6}\div10^{-7}. The branching ratios of ϕ-meson decay ϕ\to Pγis estimated to be in the range 1.8\cdot 10^{-13} ÷1.6\cdot 10^{-7}, depending on the hierarchy of supersymmetry breaking soft terms. Similar branchings for ρ- and ω-mesons are in the range 10^{-14}÷3.4\cdot 10^{-7}. | |
