Half-BPS Vertex Operators of the $Ad{S}_5\times S^5$ Superstring

Abstract

Using the pure spinor formalism for the superstring in an $Ad{S}_5\times S^5$ background, a simple expression is found for half-BPS vertex operators. At large radius, these vertex operators reduce to the usual supergravity vertex operators in a flat background. And at small radius, there is a natural conjecture for generalizing these vertex operators to non-BPS states.
