One-form Abelian gauge theory as the Hodge theory

RP Malik - International Journal of Modern Physics A, 2007 - World Scientific
We demonstrate that the two (1+ 1)-dimensional (2D) free 1-form Abelian gauge theory
provides an interesting field theoretical model for the Hodge theory. The physical …

the unification of general relativity and quantum theory. By taking advantage of recent …

Abelian 2-form gauge theory: superfield formalism

RP Malik - The European Physical Journal C, 2009 - Springer
We derive the off-shell nilpotent Becchi–Rouet–Stora–Tyutin (BRST) and anti-BRST
symmetry transformations for all the fields of a free Abelian 2-form gauge theory by …

An alternative to the horizontality condition in the superfield approach to BRST symmetries

RP Malik - The European Physical Journal C, 2007 - Springer
We provide an alternative to the gauge covariant horizontality condition, which is
responsible for the derivation of the nilpotent (anti-) BRST symmetry transformations for the …

Superfield approach to symmetries for matter fields in Abelian gauge theories

RP Malik - Journal of Physics A: Mathematical and General, 2004 - iopscience.iop.org
The derivation of the nilpotent Becchi–Rouet–Stora–Tyutin (BRST)-and anti-BRST
symmetries for the matter fields, present in any arbitrary interacting gauge theory, has been …

Superfield approach to nilpotent symmetries for QED from a single restriction: an alternative to the horizontality condition

RP Malik - Journal of Physics A: Mathematical and General, 2006 - iopscience.iop.org
We derive together the exact local, covariant, continuous and off-shell nilpotent Becchi–
Rouet–Stora–Tyutin (BRST) and anti-BRST symmetry transformations for the U (1) gauge …

Unique nilpotent symmetry transformations for matter fields in QED: augmented superfield formalism

[HTML][HTML] Chiral QED2 with Faddeevian anomaly in the context of the augmented superfield approach

S Ghoshal, A Rahaman - Nuclear Physics B, 2024 - Elsevier
We consider the bosonized version of the Chiral Schwinger model in (1+ 1) dimension with
the generalized Faddeevian anomaly, which does not have the Lorentz covariance structure …

Novel symmetries in the modified version of two dimensional Proca theory

T Bhanja, D Shukla, RP Malik - The European Physical Journal C, 2013 - Springer
By exploiting Stueckelberg's approach, we obtain a gauge theory for the two-dimensional,
that is,(1+ 1)-dimensional (2D) Proca theory and demonstrate that this theory is endowed …
