We show the possibility of realizing μ-Split supersymmetry in type IIB Swiss-Cheese Calabi-Yau (orientifold) compactifications in string theory in the presence of a space-time filling D3-brane and fluxed stacks of D7-branes wrapping the “big” divisor, generating the first-generation leptonic (including neutrino) and quark masses, heavy squarks/sleptons, heavy Higgsino, one light Higgs and one heavy Higgs. We also show that the gluinos are relatively long-lived and by estimating the half-life of the LSP - a neutralino - show that it could be a viable dark matter candidate. As an aside, using the Donaldson's algorithm, we also construct nearly Ricci-flat Swiss-Cheese metrics in the large volume limit.
