# Construction of a Massive ABJM Theory Without Higgs Superfields

## TL;DR

This paper develops a massive ABJM theory in $
abla=1$ superspace by introducing a Proca mass term, analyzing symmetry breaking and restoration, and exploring gauge dependence in the presence of mass and condensates.

## Contribution

It constructs a massive ABJM model with a Proca mass term, extending BRST symmetry to restore invariance, and investigates gauge dependence issues.

## Key findings

- Mass term breaks original BRST symmetry.
- Extended BRST restores symmetry in the massive model.
- Gauge dependence arises with mass and ghost condensates.

## Abstract

A massive Aharony-Bergman-Jafferis-Maldacena (ABJM) model in $\mathcal{N} =1$ superspace is analysed by considering a Proca type mass term into the most general Faddeev-Popov action in a covariant gauge. The presence of mass term breaks the original BRST and anti-BRST invariance of the model. Further, the symmetry of the massive ABJM model is restored by extending the BRST and anti-BRST transformations. We show that the supergauge dependence of generating functional for connected diagrams occurs in presence of mass and ghost-anti-ghost condensates in the theory.
