Enhanced Gauge Symmetries on Elliptic K 3
نویسندگان
چکیده
We show that the geometry of K3 surfaces with singularities of type AD -E contains enough information to reconstruct a copy of the Lie algebra associated to the given Dynkin diagram. We apply this construction to explain the enhancement of symmetry in F and IIA theories compactified on singular K3's.

Enhanced Gauge Symmetry in M-theory
In this article we examine some points in the moduli space of M-Theory at which there arise enhanced gauge symmetries. In particular, we examine the “trivial” points of enhanced gauge symmetry in the moduli space of M-Theory on S × S1/Z2 as well as the points of enhanced gauge symmetry in the moduli space of M-Theory on K3 and those in the moduli space of M-Theory on T 5/Z2 × S. Also, we employ...

We study the enhanced gauge symmetries at constant couplings in the moduli space of the Gimon-Polchinski Orientifold. We show that whenever there is a singularity of
متن کاملEnhanced Gauge Symmetries in Superstring Theories
Certain four-dimensional N = 4 supersymmetric theories have special vacua in which massive charged vector supermultiplets become massless, resulting in an enhanced non-abelian gauge symmetry. We show here that any two N = 4 theories having the same Bogomolnyi spectrum at corresponding points of their moduli spaces have the same enhanced symmetry groups. In particular, the K 3 × T 2 compactified...
متن کاملChan-Paton Soliton Gauge States of Compatified Open String
We study the mechanism of enhanced gauge symmetry of bosonic open string compatified on torus by analyzing the zero-norm soliton (nonzero winding of wilson line) gauge states in the spectrum. Unlike the closed string case, we find that the soliton gauge state exists only at massive levels. These soliton gauge states correspond to the existence of enhanced massive gauge symmetries with transform...
متن کاملEnhanced gauge symmetry and braid group actions
Enhanced gauge symmetry appears in Type II string theory (as well as Fand M-theory) compactified on Calabi–Yau manifolds containing exceptional divisors meeting in Dynkin configurations. It is shown that in many such cases, at enhanced symmetry points in moduli a braid group acts on the derived category of sheaves of the variety. This braid group covers the Weyl group of the enhanced symmetry a...
