Description

In this talk we present the study of sgoldstino phenomenology for sgoldstino masses 260-1000 GeV. Sgoldstinos are assumed to be produced in proton-proton collisions at the centre-of-mass energies $7-14$ TeV. We consider the impact of sgoldstino mixing with particles from Higgs sector on sgoldstino production cross section and sgoldstino branching ratio. We find a region in parameter space for which sgoldstino branching ratio is equal to $1:2:1$. In this region we can expect the increase in resonant Higgs pairs production. Using the results of experimental searches of the ATLAS and the CMS collaborations, we constrain gluino mass and scale of SUSY breaking. We also obtain the predictions for $W^+W^-$, $ZZ$ and $hh$ resonant production cross sections for $\sqrt{S}=14$ TeV.
