Twistfield Perturbations of Vertex Operators in the Z2-Orbifold Model
نویسنده
چکیده
Abstract: We apply Kadanoff’s theory of marginal deformations of conformal field theories to twistfield deformations of Z2 orbifold models in K3 moduli space. These deformations lead away from the Z2 orbifold sub-moduli-space and hence help to explore conformal field theories which have not yet been understood. In particular, we calculate the deformation of the conformal dimensions of vertex operators for h, h̃ < 1/2 in second order perturbation theory.

On vertex balance index set of some graphs
Let Z2 = {0, 1} and G = (V ,E) be a graph. A labeling f : V → Z2 induces an edge labeling f* : E →Z2 defined by f*(uv) = f(u).f (v). For i ε Z2 let vf (i) = v(i) = card{v ε V : f(v) = i} and ef (i) = e(i) = {e ε E : f*(e) = i}. A labeling f is said to be Vertex-friendly if | v(0) − v(1) |≤ 1. The vertex balance index set is defined by {| ef (0) − ef (1) | : f is vertex-friendly}. In this paper ...
متن کامل2A-orbifold construction and the baby-monster vertex operator superalgebra
In this article we prove that the full automorphism group of the baby-monster vertex operator superalgebra constructed by Höhn is isomorphic to 2×B, where B is the baby-monster sporadic finite simple group, and determine irreducible modules for the baby-monster vertex operator algebra. Our result has many corollaries. In particular, we can prove that the Z2-orbifold construction with respect to...
متن کاملA Z2-orbifold model of the symplectic fermionic vertex operator superalgebra
We give an example of an irrational C2-cofinite vertex operator algebra whose central charge is −2d for any positive integer d. This vertex operator algebra is given as the even part of the vertex operator superalgebra generated by d pairs of symplectic fermions, and it is just the realization of the c = −2-triplet algebra given by Kausch in the case d = 1. We also classify irreducible modules ...
متن کاملToward the M(F )–Theory Embedding of Realistic Free-Fermion Models
We construct a Landau–Ginzburg model with the same data and symmetries as a Z2 × Z2 orbifold that corresponds to a class of realistic free-fermion models. Within the class of interest, we show that this orbifolding connects between different Z2 ×Z2 orbifold models and commutes with the mirror symmetry. Our work suggests that duality symmetries previously discussed in the context of specific M a...
متن کامل1 Grand Unified Models on S1/(Z2 × Z ′ 2) Orbifold ∗)
We suggest two grand unified models where the fifth dimensional coordinate is compactified on an S1/(Z2 × Z ′ 2) orbifold. Before showing the models, let us see the compactification of the fifth dimension. We denote the five dimensional coordinate as y, which is compactified on an S1/(Z2 × Z ′ 2) orbifold. Under the parity transformation of Z2 and Z ′ 2, which transform y → −y and y ′ → −y (y =...
