Sgoldstino signature in $hh$, $W^+W^-$ and $ZZ$ spectra at the LHC

16 Mar 2020 Demidov S. Gorbunov D. Kriukova E.

In a supersymmetric extension of the Standard Model of particle physics (SM) with low scale of supersymmetry breaking, sgoldstino of (sub)TeV mass can be observed at the Large Hadron Collider (LHC) as a peak in diboson mass spectra. Moreover, as a singlet with respect to the SM gauge group, scalar sgoldstino can mix with the SM-like Higgs boson and interfere in all neutral channels providing with the promising signatures of new physics if superpartners are heavy...
