The stueckelberg field

H Ruegg, M Ruiz-Altaba - International Journal of Modern Physics …, 2004 - World Scientific
In 1938, Stueckelberg introduced a scalar field which makes an Abelian gauge theory
massive but preserves gauge invariance. The Stueckelberg mechanism is the introduction of …

Finite BRST transformation and constrained systems

S Upadhyay, BP Mandal - Annals of Physics, 2012 - Elsevier
We establish the connection between the generating functional for the first class theories
and the generating functional for the second class theories using the finite field dependent …

Vacuum polarization and induced Maxwell and Kalb-Ramond effective action in very special relativity

RV Maluf, GJ Olmo - Physical Review D, 2023 - APS
This work investigates the implications of very special relativity (VSR) on the calculation of
vacuum polarization for fermions in the presence of Maxwell and Kalb-Ramond gauge fields …

Anomalous chromomagnetic moment of quarks

ID Choudhury, A Lahiri - Modern Physics Letters A, 2015 - World Scientific
We do a perturbative calculation of the anomalous chromomagnetic dipole moment (CMDM)
of quarks at one-loop, considering the effect of a small mass of the gluon. We find partial …

-Dimensional topologically massive 2-form gauge theory: geometrical superfield approach

R Kumar, D Mukhopadhyay - The European Physical Journal C, 2018 - Springer
We derive the complete set of off-shell nilpotent and absolutely anticommuting Becchi–
Rouet–Stora–Tyutin (BRST) and anti-BRST symmetry transformations corresponding to the …

Dual equivalence between self-dual and topologically massive models coupled to matter in dimensions

RV Maluf, FAG Silveira, JEG Silva, CAS Almeida - Physical Review D, 2020 - APS
In this work, we revisit the duality between a self-dual nongauge invariant theory and a
topological massive theory in 3+ 1 dimensions. The self-dual Lagrangian is composed by a …

Topologically massive non-Abelian gauge theories: Constraints and deformations

E Harikumar, A Lahiri, M Sivakumar - Physical Review D, 2001 - APS
We study the relationship between three non-Abelian topologically massive gauge theories,
viz., the naive non-Abelian generalization of the Abelian model, Freedman-Townsend …

New observations in the BRST analysis of dynamical non-Abelian 2-form gauge theory

R Kumar, RP Malik - Europhysics Letters, 2011 - iopscience.iop.org
We generalize the usual gauge transformations connected with the 1-form gauge potential
to the Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST symmetry transformations for the …

Augmented superfield approach to gauge-invariant massive 2-form theory

R Kumar, S Krishna - The European Physical Journal C, 2017 - Springer
We discuss the complete sets of the off-shell nilpotent (ie s^ 2_ (a) b= 0 s (a) b 2= 0) and
absolutely anticommuting (ie s_b s_ ab+ s_ ab s_b= 0 sbsab+ sabsb= 0) Becchi–Rouet …
