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…
BRST Anomaly and Superspace Constraints of the Pure Spinor Heterotic String in a Curved Background
Osvaldo Chandia, Mario Tonin
The pure spinor heterotic string in a generic super Yang-Mills and supergravity background is considered. We determine the one-loop BRST anomaly at the cohomological level. We prov…
A Note on the Classical BRST Symmetry of the Pure Spinor String in a Curved Background
Osvaldo Chandia
The classical pure spinor version of the heterotic superstring in a supergravity and super Yang-Mills background is considered. We obtain the BRST transformations of the world-shee…
D=4 Pure Spinor Superstring and N=2 Strings
Osvaldo Chandia
We study the compactification of the pure spinor superstring down to four dimensions. We find that the compactified string is described by a conformal invariant system for both the…
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.
4-point effective actions in open and closed superstring theory
Osvaldo Chandia, Ricardo Medina
Recently the effective action for the 4-point functions in abelian open superstring theory has been derived, giving an explicit construction of the bosonic and fermionic terms of t…
