On BRST-Related Symmetries in the FLPR Model with Gribov Ambiguities
Bhabani Prasad Mandal, Sumit Kumar Rai, Ronaldo Thibes
With a recent revival, novel features of the FLPR model have been reported in the literature. A connection between those features to QCD involving the Gribov problem is explored. W…
Forms of BRST symmetry on a Prototypical First-Class System
Sumit Kumar Rai, Bhabani Prasad Mandal, Ronaldo Thibes
We obtain the various forms of BRST symmetry by using the Batalin-Fradkin-Vilkovisky formalism in a prototypical first class system. We have shown that the various forms of symmetr…
New Forms of BRST Symmetry on a Prototypical First-Class System
Bhabani Prasad Mandal, Sumit Kumar Rai, Ronaldo Thibes
We scrutinize the many known forms of BRST symmetries, as well as some new ones, realized within a prototypical first-class system. Similarities and differences among ordinary BRST…
Finite Nilpotent BRST transformations in Hamiltonian formulation
Sumit Kumar Rai, Bhabani Prasad Mandal
We consider the finite field dependent BRST (FFBRST) transformations in the context of Hamiltonian formulation using Batalin-Fradkin-Vilkovisky method. The non-trivial Jacobian of…
Noncommutative Dirac oscillator in an external magnetic field
Bhabani Prasad Mandal, Sumit Kumar Rai
We show that (2+1) dimensional noncommutative Dirac oscillator in an external magnetic field is mapped onto the same but with reduced angular frequency in absence of magnetic field…
Finite nilpotent symmetry in Batalin-Vilkovisky formalism
Bhabani Prasad Mandal, Sumit Kumar Rai, Sudhaker Upadhyay
We consider the Batalin-Vilkovisky formulation of both 1-form and 2-form gauge theories, in the context of generalized BRST transformations with finite field dependent parameter. I…
Various forms of BRST symmetry in Abelian 2-form gauge theory
Sumit Kumar Rai, Bhabani Prasad Mandal
We derive the various forms of BRST symmetry using Batalin-Fradkin-Vilkovisky approach in the case of Abelian 2-form gauge theory. We show that the so-called dual BRST symmetry is…
Off-shell nilpotent finite BRST/anti-BRST transformations
Sudhaker Upadhyay, Sumit Kumar Rai, Bhabani Prasad Mandal
We develop the off-shell nilpotent finite field dependent BRST transformations and show that for different choices of the finite field dependent parameter these connect the generat…
New forms of BRST symmetry in rigid rotor
Sumit Kumar Rai, Bhabani Prasad Mandal
We derive the different forms of BRST symmetry by using the Batalin-Fradkin-Vilkovisky formalism in a rigid rotor. The so called "dual-BRST" symmetry is obtained from usual BRST sy…
Relating the generating functionals in field/antifield formulation through finite field dependent BRST transformation
Sumit Kumar Rai, Bhabani Prasad Mandal
We study the field/antifield formulation of pure Yang Mills theory in the framework of finite field dependent BRST transformation. We show that the generating functionals correspon…
Absolute anticommutativity of the nilpotent symmetries in the Hamiltonian formalism: free Abelian 2-form gauge theory
R. P. Malik, B. P. Mandal, S. K. Rai
The celebrated Curci-Ferrari (CF) type of restrictions are invoked to obtain the off-shell nilpotent and absolutely anticommuting (anti-) BRST as well as (anti-) co-BRST symmetry t…
