Standard-like Models from D-branes
I describe the main features of new intersecting D4and D5-brane orbifold models that yield the non-supersymmetric standard model, up to vector-like matter and, in some cases, extra U(1) factors in the gauge group. There are six-stack D4-brane models that have charged-singlet scalar tachyons and which either contain all of the Yukawa couplings to the tachyonic Higgs doublets that are needed to g...
متن کاملStandard-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...
متن کاملNon-minimal Higgs content in standard-like models from D-branes at a ZN singularity
We show that attempts to construct the standard model, or the MSSM, by placing D3-branes and D7-branes at a ZN orbifold or orientifold singularity all require that the electroweak Higgs content is non-minimal. For the orbifold the lower bound on the number n(H)+n(H̄) of electroweak Higgs doublets is the number n(q L) = 6 of quark singlets, and for the orientifold the lower bound can be one less....

متن کاملD-branes and the Standard Model
We perform a systematic study of the Standard Model embedding in a D-brane configuration of type I string theory at the TeV scale. We end up with an attractive model and we study several phenomenological questions, such as gauge coupling unification, proton stability, fermion masses and neutrino oscillations. At the string scale, the gauge group is U(3)color × U(2)weak × U(1)1 × U(1)bulk. The c...
