The supersymmetric standard model from the Z6' orientifold?
Abstract
We construct N = 1 supersymmetric fractional branes on the Z6' orientifold. Intersecting stacks of such branes are needed to build a supersymmetric standard model. If a, b are the stacks that generate the SU(3)c and SU(2)L gauge particles, then, in order to obtain jthe chiral spectrum of the (supersymmetric) standard model (with nonzero Yukawa couplings to the Higgs mutiplets), it is necessary that the number of intersections a intersection b of the stacks a and b, and the number of intersections a intersection b' of a with the orientifold image b' of b satisfy (a intersection b, a intersection b') = (2, 1) or (1, 2). It is also necessary that there is no matter in symmetric representations of the gauge group. We have found a number of examples having these properties. Different lattices give different solutions and different physics.

Intersecting stacks of supersymmetric fractional branes on the Z{sub 6}{sup '} orientifold may be used to construct the supersymmetric Standard Model. We construct a fourstack model, which has the matter spectrum of the supersymmetric Standard Model, including a single pair of Higgs doublets, plus three neutrinosinglet states. However, the gauge group is SU(3){sub colour}xSU(2){sub L}xU(1){sub Y}xU(1), and there is no overall cancellation of RamondRamond tadpoles.

Getting just the supersymmetric standard model at intersecting branes on the Z{sub 6} orientifold
In this paper, globally N=1 supersymmetric configurations of intersecting D6branes on the Z{sub 6} orientifold are discussed, involving also fractional branes. It turns out rather miraculously that one is led almost automatically to just one particular class of five stack models containing the standard model gauge group, which all have the same chiral spectrum. The further discussion shows that these models can be understood as exactly the supersymmetric standard model without any exotic chiral symmetric/antisymmetric matter. The superpartner of the Higgs finds a natural explanation and the hypercharge remains massless. However, the nonchiral spectrum within the model class is verymore » 
Neutrino fluxes from constrained minimal supersymmetric standard model lightest supersymmetric particle annihilations in the Sun
We evaluate the neutrino fluxes to be expected from neutralino lightest supersymmetric particle (LSP) annihilations inside the Sun, within the minimal supersymmetric extension of the standard model with supersymmetrybreaking scalar and gaugino masses constrained to be universal at the grand unified theory scale [the constrained minimal supersymmetric standard model (CMSSM)]. We find that there are large regions of typical CMSSM (m{sub 1/2},m{sub 0}) planes where the LSP density inside the Sun is not in equilibrium, so that the annihilation rate may be far below the capture rate. We show that neutrino fluxes are dependent on the solar model at themore » 
Minimal supersymmetric standard model and large tan[beta] from SUSY trinification
We construct a supersymmetric model based on the semisimple gauge group SU(3)[sub [ital c]][times]SU(3)[sub [ital L]][times]SU(3)[sub [ital R]] with the relation tan[beta][congruent][ital m][sub [ital t]]/[ital m][sub [ital b]] automatically arising from its structure. The model below a scale [similar to]10[sup 16] GeV naturally gives rise just to the minimal supersymmetric standard model and therefore to the presently favored values for sin[sup 2][theta][sub [ital W]] and [alpha][sub [ital s]] without fields in representations higher than the fundamental.
