String Junction Transitions in the Moduli Space of N=2 SYM

TL;DR

This paper investigates how BPS states in N=2 SU(2) Super-Yang-Mills theory transition between different string configurations in the moduli space, highlighting the role of string creation phenomena.

Contribution

It demonstrates string junction transitions within the D3-brane model of N=2 SU(2) SYM, revealing new insights into the moduli space dynamics of BPS states.

Findings

Transitions between open strings and string webs are demonstrated.

String creation phenomena drive these transitions.

Results enhance understanding of BPS state behavior in moduli space.

Abstract

The string theory description of BPS states in D-brane world-volume field theories may undergo transitions from open strings to string webs, as well as between different string webs, as one moves in the field theory moduli space. These transitions are driven by the string creation phenomenon. We demonstrate such transitions in the D3-brane realization of N=2 SU(2) Super-Yang-Mills theory.
