Towards the correct prescription of the Problem of divergence of Propagator of Siegal-Zwiebach action from String theory in Fierz-Pauli Gauge in the small mass limit
Vipul Kumar Pandey
In the present work we will give an explicit solution the problem of divergence of propagator of gauge-invariant Siegel-Zwiebach action in Fierz-Pauli gauge in massless limit by co…
Symplectic Quantization and General Constraint Structure of a Prototypical Second-Class System
Ignacio S. Gomez, Vipul Kumar Pandey, Ronaldo Thibes
We discuss a general prototypical constrained Hamiltonian system with a broad application in quantum field theory and similar contexts where dynamics is defined through a functiona…
Small mass graviton propagator via finite-field-dependent BRST transformations in the critical dimension Siegel-Zwiebach action from string theory
Vipul Kumar Pandey, Ronaldo Thibes
We discuss the divergent graviton propagator massless limit problem in and show how it can be rigorously approached by interconnecting distinct gauge-fixed Siegel-Zwiebach g…
BFV quantization and BRST symmetries of the gauge invariant fourth-order Pais-Uhlenbeck oscillator
Bhabani Prasad Mandal, Vipul Kumar Pandey, Ronaldo Thibes
We perform the BFV-BRST quantization of the fourth-order Pais-Uhlenbeck oscillator (PUO). We show that although the PUO is not naturally constrained in the sense of Dirac-Bergmann,…
BFFT Nonlinear Constraints Abelianization of a Prototypical Second-Class System
Vipul Kumar Pandey, Ronaldo Thibes
We apply the BFFT formalism to a prototypical second-class system, aiming to convert its constraints from second- to first-class. The proposed system admits a consistent initial se…
Hamiltonian and Lagrangian BRST quantization in Riemann Manifold II
Vipul Kumar Pandey
We have previously developed the BRST quantization on the hypersurface embedded in N dimensional Euclidean space in both Hamiltonian and Lagrangian formulation. We…
Hamiltonian and Lagrangian BRST quantization in Riemann Manifold
Vipul Kumar Pandey
The BRST quantization of particle motion on the hypersurface embedded in Euclidean space is carried out both in Hamiltonian and Lagrangian formalism. Using Batali…
BRST-BFV and BRST-BV Descriptions for Bosonic Fields with Continuous Spin on
C. Burdik, V. K. Pandey, A. Reshetnyak
Gauge-invariant descriptions for a free bosonic scalar field of continuous spin in a -dimensional Minkowski space-time using a metric-like formulation are constructed on the bas…
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…
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…
Maximal Abelian gauge and a generalized BRST transformation
Shinichi Deguchi, Vipul Kumar Pandey, Bhabani Prasad Mandal
We apply a generalized Becchi-Rouet-Stora-Tyutin (BRST) formulation to establish a connection between the gauge-fixed Yang-Mills (YM) theories formulated in the Lorenz gaug…
