The gauge dual of Romans mass

TL;DR

This paper explores the holographic duality between ABJM theory and type IIA string theory by introducing a non-zero Romans mass, leading to new dual theories with varied supersymmetry and flavor symmetries.

Contribution

It identifies the dual of the Romans mass in the ABJM holographic setup as the sum of the Chern-Simons levels, expanding the understanding of deformations in holographic dualities.

Findings

Four distinct theories with different supersymmetry levels identified

Romans mass F_0 corresponds to sum of Chern-Simons levels

Deformation leads to new dual theories with varied symmetries

Abstract

We deform the recently proposed holographic duality between the ABJM N=6 Chern-Simons-matter theory and type IIA string theory in AdS4xCP3. We add a non-zero Romans mass F_0, whose dual we identify as the sum of the Chern-Simons levels for the two gauge groups. One can naturally identify four different theories, with different amounts of supersymmetry and of flavor symmetry.
