Findings

Derived Lorentz-covariant algebra of constraints

Established a first rank BRST charge for the system

Provided a new theoretical framework for null superbranes

Abstract

We consider a model for tensionless (null) super p-branes in the Hamiltonian approach and in the framework of a harmonic superspace. The obtained algebra of Lorentz-covariant, irreducible, first class constraints is such that the BRST charge corresponds to a first rank system.
