Standard-like Models from Intersecting D5-branes

We construct intersecting D5-brane orbifold models that yield the (non-supersymmetric) standard model up to vector-like matter and charged-singlet scalars. The models are constrained by the requirement that twisted tadpoles cancel, and that the gauge boson coupled to the weak hypercharge U(1)Y does not get a string-scale mass via a generalised Green-Schwarz mechanism. Gauge coupling constant ra...

Intersecting Branes in Matrix Theory

We construct BPS states in the matrix description of M-theory. Starting from a set of basic M-theory branes, we study pair intersections which preserve supersymmetry. The fractions of the maximal supersymmetry obtained in this way are 1 2 , 1 4 , 1 8 , 3 16 and 1 16. In explicit examples we establish that the matrix BPS states correspond to (intersecting) brane configurations that are obtained ...

An Index for Intersecting Branes in Matrix Models

We introduce an index indicating the occurrence of chiral fermions at the intersection of branes in matrix models. This allows to discuss the stability of chiral fermions under perturbations of the branes.

More about the Standard Model at Intersecting Branes 1

Intersecting D-brane models seem to be one of the most promising avenues to embed the Standard Model physics within the string context. We review here different aspects of these models. Topics include the question of SUSY and quasi-SUSY in intersecting brane models, model-building, the brane recom-bination interpretation of the SM Higgs mechanism, Yukawa couplings, the lowering of the string sc...

Standard Model at Intersecting D5-branes : Lowering the String Scale

Recently a class of Type IIA orientifold models was constructed yielding just the fermions of the SM at the intersections of D6-branes wrapping a 6-torus. We generalize that construction to the case of Type IIB compactified on an orientifold of T × (C/ZN) with D5-branes intersecting at angles on T. We construct explicit models in which the massless fermion spectrum is just the one of a three-ge...
