Finite field-dependent BRST symmetry for ABJM theory in ${\cal N}=1$ superspace

Understand

In this paper we analyse the ABJM theory in ${\cal N}=1$ superspace.

• Firstly we study the linear and non-linear BRST transformations for the ABJM theory.
• Then we derive the finite field dependent version of these BRST (FFBRST) transformations.
• Further we show that such FFBRST transformations relate the generating functional in linear gauge to the generating functional in the non-linear gauge of ABJM theory.
