The conformal gauge to the derivative gauge for worldsheet gravity
Sudhaker Upadhyay
The BRST quantizations of worldsheet gravity corresponding to final more acceptable derivative gauge and the standard conformal gauge are studied. We establish a mapping between th…
Finite field-dependent BRST symmetry for ABJM theory in superspace
Mir Faizal, Sudhaker Upadhyay, Bhabani Prasad Mandal
In this paper we analyse the ABJM theory in superspace. Firstly we study the linear and non-linear BRST transformations for the ABJM theory. Then we derive the finite…
Generalized BRST symmetry for arbitrary spin conformal field theory
Sudhaker Upadhyay, Bhabani Prasad Mandal
We develop the finite field-dependent BRST (FFBRST) transformation for arbitrary spin-s conformal field theories. We discuss the novel features of the FFBRST transformation in thes…
Spontaneous Breaking of the BRST Symmetry in the ABJM theory
Mir Faizal, Sudhaker Upadhyay
In this paper, we will analyse the ghost condensation in the ABJM theory. We will perform our analysis in superspace. We show that in the Delbourgo-Jarvis-Baulieu-Thie…
Emergence of Lowenstein-Zimmermann mass terms for QED
Sudhaker Upadhyay, Manoj Kumar Dwivedi, Bhabani Prasad Mandal
In this paper we consider a super-renormalizable theory of massless QED in dimensions and discuss their BRST symmetry transformation. By extending the BRST transformation w…
ABJM theory in Batalin-Vilkovisky formulation
Sudhaker Upadhyay, Diptarka Das
We analyze the quantum ABJM theory on superspace in different gauges. We study the Batalin-Vilkovisky (BV) formulation for this model. By developing field/antifield…
