Abstract

The phenomenology of the simplest processes involving sgoldstino 260–1000 GeV in mass is studied. The effect of the sgoldstino–Higgs mixing on sgoldstino branching ratio and the cross-section of its production in proton–proton collisions is considered. The characteristic mode with the sgoldstino branching ratio of 1 : 2 : 1 was distinguished. It is interesting by the enhanced resonant Higgs boson pair production. Constraints to the model parameters are determined.
