The BV Quantisation of Superparticles Type I and II

Original · EN

This letter discusses the BRST cohomology of superparticles type I and II. It was used an extended super-space to construct S0(9,1) superparticle actions that lead to super-wave functions whose spinor components satisfy S0(9,1) covariant constraints. Their BRST charges were found by using BV methods, since the models present a large number of symmetries and only close on-shell. It is shown that the zero ghost-number cohomology class of both models reproduce the same spectrum as that of N=1 ten dimensional super-Yang-Mills theory.
