Rotated Branes and N=1 Duality

TL;DR

This paper explores how rotated NS-brane configurations can model four-dimensional N=1 super-QCD theories and provide insights into N=1 duality through string theory constructions.

Contribution

It introduces a family of brane setups that interpolate between known vacua and duality configurations, linking geometric rotations to supersymmetry breaking.

Findings

Brane configurations correspond to N=1 super-QCD theories.

Rotation angle relates to N=2 breaking parameter and adjoint mass.

Comments on potential stringy proofs of N=1 duality.

Abstract

We consider configurations of rotated NS-branes leading to a family of four-dimensional N=1 super-QCD theories, interpolating between four-dimensional analogues of the Hanany-Witten vacua, and the Elitzur-Giveon-Kutasov configuration for N=1 duality. The rotation angle is the N=2 breaking parameter, the mass of the adjoint scalar in the N=2 vector multiplet. We add some comments on the relevance of these configurations as possible stringy proofs of N=1 duality.
