Covariant BRS quantization of the ten-dimensionalN=1Brink-Schwarz superparticle

Abstract
We perform the covariant Becchi-Rouet-Stora quantization of the N=1 Brink-Schwarz superparticle in ten dimensions. The key ideas used are (1) the Batalin-Fradkin formalism for second-class constraints, (2) nonsquare vielbeins relating spinor indices to internal SO(8) indices, and (3) the special properties of Γ matrices in ten dimensions. Our work generalizes Eisenberg and Solomon’s solution of the N=2 case to N=1.
