摘要：

We construct N = I supersymmetric fractional branes on the Z(6)' 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 just the chiral spectrum of the (supersymmetric) Standard Model (with non-zero Yukawa couplings to the Higgs multiplets), it is necessary that the number of intersections a circle b of the stacks a and b, and the number of intersections a circle b' of a with the orientifold image b' of b satisfy (a circle b, a circle b') = +/-(2, 1) or +/-(1, 2). It is also necessary that there is no matter in symmetric representations of the gauge group, and not too much matter in antisymmetric representations, on either stack. We provide a number of examples having these properties. Different lattices give different solutions and different physics. (c) 2006 Elsevier B.V. All rights reserved.
