Deconstructing (2,0) Proposals

TL;DR

This paper analyzes and clarifies the relationships between different proposals for understanding the six-dimensional (2,0) theory, showing how they connect through deconstruction and compactification of five-dimensional maximally supersymmetric Yang-Mills.

Contribution

It demonstrates the equivalence and connections between three different proposals for the (2,0) theory, clarifying their relationships and underlying structures.

Findings

hep-th/0110146 provides a deconstruction of 5D maximally supersymmetric Yang-Mills

The subset of degrees of freedom in hep-th/9707079 and hep-th/9712117 matches the DLCQ approach

Compactification of certain proposals aligns with the DLCQ from other approaches

Abstract

We examine the relationships between three proposals for the six-dimensional (2,0) theory: the DLCQ of hep-th/9707079, hep-th/9712117, the deconstruction prescription of hep-th/0110146, and the five-dimensional maximally supersymmetric Yang-Mills proposal of 1012.2880, 1012.2882. We show that hep-th/0110146 gives a deconstruction of five-dimensional maximally supersymmetric Yang-Mills. The proposal of hep-th/9707079, hep-th/9712117 uses a subset of the degrees of freedom of five-dimensional Yang-Mills and we show that compactification of it on a circle of finite radius agrees with the DLCQ arising from the proposal of 1012.2880, 1012.2882 or from the deconstruction proposal of hep-th/0110146.
