BRST BMS4 symmetry and its cocycles from horizontality conditions
The BRST structure of the extended Bondi-Metzner-Sachs symmetry group of asymptotically flat manifolds is investigated using the recently introduced...

Spectrum, Vertices, and BRST Quantization
We present the modern covariant quantization of perturbative string theory á la BRST. We determine the physical spectrum of the several string...

BRST symmetry and the convolutional double copy
Motivated by the results of Anastasiou et al., we consider the convolutional double copy for BRST and anti-BRST covariant formulations of...

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...

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...

Cubic interactions of d4 irreducible massless higher spin fields within BRST approach
We develop an approach to constructing the manifestly Lorentz covariant cubic interaction vertices for the four-dimensional massless higher spin...
