Threebranes in twelve dimensions

TL;DR

This paper explores the theoretical framework of super-threebranes in twelve-dimensional spacetime, clarifying their features and connections to M-2-branes and type IIB superstrings through reduction.

Contribution

It introduces a super-threebrane model in (10,2) signature spacetime, detailing the superspace and spinor structures, and elucidates their relation to known brane theories.

Findings

Clarified features of super (2+2)-brane in (10,2) spacetime

Connected super-threebrane to M-2-brane and type IIB superstring

Discussed superspace and spinor constructions for the brane action

Abstract

In this note we discuss the theory of super-threebranes in a spacetime of signature (10,2). Upon reduction, the threebrane provides us with the classical representations of the M-2-brane and the type IIB superstring. Many features of the original super (2+2)-brane theory are clarified. In particular, the (10,2) superspace and the spinors required to construct the brane action are discussed.
