CHIRAL SUPERPARTICLE AND THE FULL SET OF (1, 0) SUPERGRAVITY CONSTRAINTS

We present BFV quantization of manifestly Lorentz-covariant chiral par ticle action. Lagrangians for (1,1), (1,0), (0,1) chiral superparticle s (CSP) invariant under the local Siegel-type transformations are cons idered; the mechanism of closing of local Siegel k-symmetry algebra in Lagrangian formulation for the (1,0) CSP is suggested. The full set o f (1,0) supergravity constraints is obtained from the requirement of p reserving local symmetries in a curved background. The possibility of extending the results to D = 10 case is discussed.
