3D Jackiw–Pi model: (anti-)chiral superfield approach to BRST formalism
We discuss and derive the continuous Becchi–Rouet–Stora–Tyutin (BRST) and anti-BRST symmetry transformations for the Jackiw–Pi (JP) model of three (2...

Geometric BV for twisted Courant sigma models and the BRST power finesse
We study twisted Courant sigma models, a class of topological field theories arising from the coupling of 3D 0-/2-form BF theory and Chern-Simons...

Unfree Gauge Symmetry
AbstractThe gauge symmetry is said unfree if the gauge transformation leaves the action functional unchanged provided for the gauge parameters are...

Renormalisation group equations for BRST-restored chiral theory in dimensional renormalisation: application to two-loop chiral-QED
We discuss how renormalisation group equations can be consistently formulated using the algebraic renormalisation framework, in the context of a...
