κsymmetry and Bogomol'ny bound
Abstract
By applying the twistorlike transform to the GS superstring theory we fix the local fermionic gauge symmetry, known as κsymmetry. Fixing the κsymmetry in the GS superstring theory and the N = 1 worldsheet supersymmetry in the NSR theory proves the relation between these theories, conjectured earlier; the GS fermionic variable θ is shown to be related to the NSR worldsheet fermionic variable ψ through the twistor field Λ. Upon fixing the κsymmetry we derive the gaugefixed expressions for the supercharges (corresponding to spinor representations of SO(8)) and analyze the gaugefixed spacetime superalgebra. The analysis relates the κinvariance to the Bogomol'nytype condition, with the former appearing as a spacetime superpartner of the latter. The BPS saturation appears to be crucial for the nonperturbative formulation of the κsymmetry. The relation to the RR charges of pbrane solutions of the D = 10 supergravity is discussed.
