Construction of a Massive ABJM Theory Without Higgs Superfields

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.Comment: 9 pages, no figur

Innovative Supplier Selection: Key Success Factors

Due  to  the  emergence  of  globalization  and  shrinking  distances, companies don’t  mind  going   to new unexplored locations in search of suitable suppliers. However, the suitability of suppliers can be measured in terms of its technical competence and innovativeness. The aim of this paper is to find out the necessary parameters to check the innovativeness of suppliers. This paper looks at how the authors analyzed existing literature on supplier selection based on their innovativeness

Reducible gauge theories in very special relativity

In this paper we analyze the tensor field (reducible gauge) theories in the context of very special relativity (VSR). Particularly, we study the VSR gauge symmetry as well as VSR BRST symmetry of Kalb-Ramond and Abelian 3-form fields involving a fixed null vector. We observe that the Kalb-Ramond and Abelian 3-form fields and corresponding ghosts get masses in VSR framework. The effective action in VSR-type axial gauge is greatly simplified compared with the VSR-type Lorenz gauge. Further, we quantize these models using a Batalin-Vilkovisy (BV) formulation in VSR.Comment: 14 pages, no figure, Version to appear in EPJ

Field-dependent quantum gauge transformation

In this paper we generalize the quantum gauge transformation of Maxwell theory obtained through gaugeon formalism. The generalization is made by making the bosonic transformation parameter field-dependent. The Jacobian of vacuum functional under field-dependent quantum gauge transformation is calculated explicitly. We show that the quantum gauge transformation with a particular choice of field-dependent parameter connects the gaugeon actions of Maxwell theory in two different gauges. We establish the result by connecting two well-known gauges, namely, Lorentz gauge and axial gauge.Comment: 7 pages, No figure, Journal versio
