We show that it is possible to realize a "mu-split SUSY" scenario [1] in thecontext of large volume limit of type IIB compactifications on Swiss-CheeseCalabi-Yau's in the presence of a mobile space-time filling D3-brane and a(stack of) D7-brane(s) wrapping the "big" divisor Sigma_B. For this, weinvestigate the possibility of getting one Higgs to be light while other to beheavy in addition to a heavy Higgsino mass parameter. Further, we examine theexistence of long lived gluino that manifests one of the major consequences ofmu-split SUSY scenario, by computing its decay width as well as lifetimecorresponding to the 3-body decays of the gluino into a quark, a squark and aneutralino or Goldstino, as well as 2-body decays of the gluino into either aneutralino or a Goldstino and a gluon. Guided by the geometric Kaehlerpotential for Sigma_B obtained in [2] based on GLSM techniques, and theDonaldson's algorithm [3] for obtaining numerically a Ricci-flat metric, wegive details of our calculation in [4] pertaining to our proposed metric forthe full Swiss-Cheese Calabi-Yau, but for simplicity of calculation, close toSigma_B, which is Ricci-flat in the large volume limit. Also, as an applicationof the one-loop RG flow solution for the Higgsino mass parameter, we show thatthe contribution to the neutrino masses at the EW scale from dimension-sixoperators arising from the Kaehler potential, is suppressed relative to theWeinberg-type dimension-five operators.
