A perturbative study of holographic mABJM theory

Abstract

Recently the calculation of holographic free energy for mass-deformed ABJM model (mABJM) with N=2 supersymmetry and SU(3)×U(1) global symmetry was tackled by Bobev et al. [1]. We solve the associated BPS equations, requiring IR regularity, using a perturbative method proposed by one of us in [2]. In particular, we provide an analytic proof of a crucial conjecture made in [1] based on numerical solutions: that the R-charge values of three chiral multiplets in mABJM should be independent of the IR values of a hypermultiplet scalar, which is holographically dual to the superpotential mass term.
