Query: A Realistic Intersecting D6-Brane Model after the First LHC Run   With the Higgs boson mass around 125 GeV and the LHC supersymmetry search
constraints, we revisit a three-family Pati-Salam model from intersecting
D6-branes in Type IIA string theory on the $\mathbf{T^6/(\Z_2 \times \Z_2)}$
orientifold which has a realistic phenomenology. We systematically scan the
parameter space for $\mu<0$ and $\mu>0$, and find that the gravitino mass is
generically heavier than about 2 TeV for both cases due to the Higgs mass low
bound 123 GeV. In particular, we identify a region of parameter space with the
electroweak fine-tuning as small as $\Delta_{EW} \sim$ 24-32 (3-4$\%$). In the
viable parameter space which is consistent with all the current constraints,
the mass ranges for gluino, the first two-generation squarks and sleptons are
respectively $[3, ~18]$ TeV, $[3, ~16]$ TeV, and $[2, ~7]$ TeV. For the
third-generation sfermions, the light stop satisfying $5\sigma$ WMAP bounds via
neutralino-stop coannihilation has mass from 0.5 to 1.2 TeV, and the light stau
can be as light as 800 GeV. We also show various coannihilation and resonance
scenarios through which the observed dark matter relic density is achieved.
Interestingly, the certain portions of parameter space has excellent
$t$-$b$-$\tau$ and $b$-$\tau$ Yukawa coupling unification. Three regions of
parameter space are highlighted as well where the dominant component of the
lightest neutralino is a bino, wino or higgsino. We discuss various scenarios
in which such solutions may avoid recent astrophysical bounds in case if they
satisfy or above observed relic density bounds. Prospects of finding
higgsino-like neutralino in direct and indirect searches are also studied. And
we display six tables of benchmark points depicting various interesting
features of our model.
