Compactification of the Heterotic Pure Spinor Superstring I
Osvaldo Chandia, William D. Linch, Brenno Carlini Vallilo
In this paper we begin the study of compactifications of the pure spinor formalism for superstrings. As a first example of such a process we study the case of the heterotic string…
On the Non-renormalization of the AdS Radius
Luca Mazzucato, Brenno Carlini Vallilo
We show that the relation between the 't Hooft coupling and the radius of AdS is not renormalized at one-loop in the sigma model perturbation theory. We prove this by computing the…
Integrability of the Gauged Linear Sigma Model for AdS_5xS^5
William D. Linch, Brenno Carlini Vallilo
Recently, a gauged linear sigma model was proposed by Berkovits and Vafa which can be used to describe the AdS_5xS^5 superstring at finite and zero radius. In this paper we show th…
Conformal Invariance of the Pure Spinor Superstring in a Curved Background
Osvaldo Chandia, Brenno Carlini Vallilo
It is shown that the pure spinor formulation of the heterotic superstring in a generic gravitational and super Yang-Mills background has vanishing one-loop beta functions.
One Loop Conformal Invariance of the Superstring in an AdS_5 x S^5 Background
Brenno Carlini Vallilo
It is proven that the pure spinor superstring in an AdS_5 x S^5 background remains conformally invariant at one loop level in the sigma model perturbation theory.
