The Self-Dual String Soliton

TL;DR

This paper constructs a supersymmetric self-dual string soliton in M-theory fivebrane equations, then derives related brane solutions through dimensional reduction, advancing understanding of solitonic objects in string/M-theory.

Contribution

It introduces a new BPS self-dual string soliton solution in M-theory fivebrane equations and connects it to lower-dimensional brane solutions via dimensional reduction.

Findings

Derived a BPS self-dual string soliton in M-theory.

Connected the soliton to 0-brane and (p-2)-brane solutions.

Enhanced understanding of solitonic objects in string/M-theory.

Abstract

We obtain a BPS soliton of the M theory fivebrane's equations of motion representing a supersymmetric self-dual string. The resulting solution is then dimensionally reduced and used to obtain 0-brane and (p-2)-brane solitons on D-p-branes.
