A (1,2) Heterotic String with Gauge Symmetry
We construct a (1,2) heterotic string with gauge symmetry and determine its particle spectrum. This theory has a local N=1 worldsheet supersymmetry for left movers and a local N=2 worldsheet supersymmetry for right movers and describes particles in either two or three space-time dimensions. We show that fermionizing the bosons of the compactified N=1 space leads to a particle spectrum which has...
متن کاملA Supersymmetric Model with the Gauge Symmetry
A supersymmetric model with two copies of the Standard Model gauge groups is constructed in the gauge mediated supersymmetry breaking scenario. The supersymmetry breaking messengers are in a very simple form. The Standard Model is obtained after first step gauge symmetry breaking. In the case of one copy of the gauge interactions being strong, a scenario of electroweak symmetry breaking is disc...
متن کاملOn gauge/string correspondence and mirror symmetry
We consider a mirror dual of the Berkovits-Vafa A-model for the BPS superstring on AdS5 × S 5 in the form of a deformed superconifold. Via geometric transition, the theory has a dual description as the hermitian gaussian one-matrix model. We show that the A-model amplitudes of AdS2 × S 4 branes, breaking the superconformal symmetry as U(2, 2|4) → OSp(4∗|4), are evaluated in terms of observables...
متن کاملEnhanced Gauge Symmetry in Type II String Theory
We show how enhanced gauge symmetry in type II string theory compactified on a Calabi–Yau threefold arises from singularities in the geometry of the target space. When the target space of the type IIA string acquires a genus g curve C of AN−1 singularities, we find that an SU(N) gauge theory with g adjoint hypermultiplets appears at the singularity. The new massless states correspond to soliton...
متن کاملS-Duality as an Open String Gauge Symmetry
We demonstrate and discuss the connection between S-duality and string-theoretic picture-changing gauge transformation in the “infinite momentum frame”. The picturechanging transformation at zero momentum leads to the presence of the topological 5-form charge in the type IIB superalgebra (dimensionally reduced SUSY algebra of M-theory) which is attributed to the M5-brane. The topological charge...
