A Quantum Mechanical Example for Hodge Theory
Shri Krishna, R. P. Malik
On the basis of (i) the discrete and continuous symmetries (and corresponding conserved charges), (ii) the ensuing algebraic structures of the symmetry operators and conserved char…
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…
Augmented Superfield Approach to Gauge-invariant Massive 2-Form Theory
R. Kumar, S. Krishna
We discuss the complete sets of the off-shell nilpotent (i.e. s^2_{(a)b} = 0) and absolutely anticommuting (i.e. s_b s_{ab} + s_{ab} s_b = 0) Becchi-Rouet-Stora-Tyutin (BRST) (s_b)…

Charanjit S. Aulakh, Ram Lal Awasthi, S. Krishna
We list operators of the superpotential of the effective MSSM that emerges from the NMSGUT up to sextic degree. We give illustrative expressions for the coefficients in terms of NM…

A. Shukla, S. Krishna, R. P. Malik
We derive the off-shell nilpotent and absolutely anticommuting Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST symmetry transformations, corresponding to the (1-form) Yang-Mills (YM…
General N = 2 Supersymmetric Quantum Mechanical Model: Supervariable Approach to its Off-Shell Nilpotent Symmetries
S. Krishna, A. Shukla, R. P. Malik
Using the supersymmetric (SUSY) invariant restrictions on the (anti-)chiral supervariables, we derive the off-shell nilpotent symmetries of the general one (0 + 1)-dimensional N =…

S. Krishna, A. Shukla, R. P. Malik
We derive the on-shell as well as off-shell nilpotent supersymmetric (SUSY) symmetry transformations for the N = 2 SUSY quantum mechanical model of a one (0 + 1)-dimensional (1D) f…
