In the covariant lattice formalism, chiral four-dimensional heterotic string vacua are obtained from certain even self-dual lattices which completely decompose into a left-mover and a right-mover lattice. The main purpose of this work is to classify all right-mover lattices that can appear in such a chiral model, and to study the corresponding left-mover lattices using the theory of lattice.
The dimensions of chiral primary operators at superconformal points the seiberg-witten curve as the twisted superpotential of the worldsheet theory. By studying the worldsheet theory of the vortex string, we can reconstruct the following results about four dimensional gauge theories:.

As expected, in on orbifolds [4,5] yield chiral gauge theories in four dimensions including the standard.
The corresponding four-dimensional theory, which may subsequently be compared to observations. Among superstring theories the heterotic string [5] has always been considered as the most promis- ing version in the prospect to find contact with low-energy physics studied in accelerators, mainly.
We'll start with some stereoisomeric four-carbon sugars with two chiral centers. To avoid confusion, we will simply refer to the different stereoisomers by capital.

Four-dimensional heterotic strings and eovariant lattices the formulation of the d-dimensional (d ~ 10) heterotic string in the covariant lattice approach originates in the work of friedan, martinec and shenker [15] about the construction of covariant vertex operators for the fermionic string.
This would mean that there are 8 stereoisomers, except that 1,3-dimethylcyclopentane is an achiral.
A similar analysis of the effective four-dimensional supergravity is performed. Further evidence for the proposed one-loop correction to the stability condition is found by identifying the heterotic corrections as the s-dual of the perturbative part of $\pi$-stability as the correct stability concept in type iib theory.
