There and back again: A T-brane's tale

TL;DR

This paper explores the dual descriptions of T-branes, showing that when scalar VEVs are large, they can be effectively described as single Dp-branes with curved worldvolumes, revealing new geometric insights.

Contribution

It demonstrates a novel duality where large scalar VEVs in T-branes correspond to curved single Dp-branes, expanding understanding of their geometric and physical properties.

Findings

Large scalar VEVs lead to single curved Dp-brane descriptions.

T-dualities reveal new brane configurations.

The geometric encoding of T-brane data through curvature.

Abstract

T-branes are supersymmetric configurations described by multiple Dp-branes with worldvolume flux and non-commuting vacuum expectation values for two of the worldvolume scalars. When these values are much larger than the string scale this description breaks down. We show that in this regime the correct description of T-branes is in terms of a single Dp-brane, whose worldvolume curvature encodes the T-brane data. We present the tale of the journey to reach this picture, which takes us through T-dualities and rugby-ball-shaped brane configurations that no eye has gazed upon before.
