  Results are presented of a search for a "natural" supersymmetry scenario with
gauge mediated symmetry breaking. It is assumed that only the supersymmetric
partners of the top quark (the top squark) and the Higgs boson (higgsino) are
accessible. Events are examined in which there are two photons forming a Higgs
boson candidate, and at least two b-quark jets. In 19.7 inverse femtobarns of
proton-proton collision data at sqrt(s) = 8 TeV, recorded in the CMS
experiment, no evidence of a signal is found and lower limits at the 95%
confidence level are set, excluding the top squark mass below 360 to 410 GeV,
depending on the higgsino mass.
