Search for pair-produced higgsinos decaying via Higgs or $Z$ bosons to final states containing a pair of photons and a pair of $b$-jets with the ATLAS detector

ATLAS Collaboration

A search is presented for the pair production of higgsinos $\tilde{\chi }$ in gauge-mediated supersymmetry models, where the lightest neutralinos ${\tilde{\chi }}_1^0$ decay into a light graviti…
