Аннотация:We further discuss possible sgoldstino interpretation of the observation, reported by the HyperCP collaboration, of three Sigma(+) -> p mu(+)mu(-) decay events with the dimuon invariant mass 214.3 MeV within the detector resolution. With a sgoldstino mass equal to 214.3 MeV, this interpretation can be verified at existing and future B and phi 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)-10(-7). The branching ratios of phi meson decay phi -> P gamma are estimated to be in the range 1.8 X 10(-13)-1.6 x 10(-7), depending on the hierarchy of supersymmetry-breaking soft terms. Similar branching ratios for rho and omega mesons are in the range 10(-14)-3.4 x 10(-7).
