Conformal to Harmonic Gauge for Bosonic Strings
Vipul Kumar Pandey, Bhabani Prasad Mandal
We consider Polyakov theory of Bosonic strings in conformal gauge which are used to study conformal anomaly. However it exhibits ghost number anomaly. We show how this anomaly can…
Equivalence of two solutions of physical massive gravity
Haresh Raval, Krishnanand Kr. Mishra, Bhabani Prasad Mandal
We study some aspects of linearized gravity as gauge theory, with massive deformation. Recently it has been shown that there are two distinct solutions, which represent physical ma…
A Massive Field-Theoretic Model for Hodge Theory
S. Krishna, R. Kumar, R. P. Malik
Within the framework of Becchi-Rouet-Stora-Tyutin (BRST) formalism, we show that the four -dimensional (4D) massive Abelian 2-form gauge theory (without any interaction with…
Generalized quantum electrodynamics in the framework of Generalized BRST transformation
Krishnanand Kr. Mishra, Bhabani Prasad Mandal
Podolsky's electromagnetism which explains some of unresolved problems of usual QED has been investigated in the framework of finite field dependent (FFBRST) BRST transformation. I…
Weyl Degree of Freedom in The Nambu-Goto String Through Field Transformation
Vipul Kumar Pandey, Bhabani Prasad Mandal
We show how Weyl degrees of freedom, can be introduced in the Nambu-Goto string in the path integral formulation using reparametrization invariant measure. We first identify Weyl d…
Deconfinement to Confinement as PT phase transition
Haresh Raval, Bhabani Prasad Mandal
We consider SU(N) QCD in a new quadratic gauge which highlights certain characteristic of the theory in the non-perturbative sector. By considering natural hermiticity property of…
