Heterotic p-branes from Massive Sigma Models

TL;DR

This paper constructs supersymmetric sigma models that describe heterotic p-brane solitons, including known gauge 5-branes and new 1-brane solutions, advancing understanding of brane dynamics in string theory.

Contribution

It introduces explicit massive (0,4) supersymmetric ADHM sigma models for heterotic p-branes, revealing new solutions and extending the framework for brane constructions.

Findings

Constructed heterotic p-brane sigma models with conformal fixed points.

Discovered a new 1-brane solution preserving 1/4 supersymmetry.

Reproduced gauge 5-brane as a fixed point of the model.

Abstract

We explicitly construct massive (0,4) supersymmetric ADHM sigma models which have heterotic p-brane solitons as their conformal fixed points. These yield the familiar gauge 5-brane and a new 1-brane solution which preserve 1/2 and 1/4 of the spacetime supersymmetry respectively. We also discuss an analogous construction for the type II NS-NS p-branes using (4,4) supersymmetric models.
