Yang-Mills Chern-Simons Corrections From The Pure Spinor Superstring
نویسنده
چکیده
Nilpotency of the pure spinor BRST operator in a curved background implies superspace equations of motion for the background. By computing one-loop corrections to nilpotency for the heterotic sigma model, the Yang-Mills Chern-Simons corrections to the background are derived.

Covariant Quantization of the Superparticle using Pure
The ten-dimensional superparticle is covariantly quantized by constructing a BRST operator from the fermionic Green-Schwarz constraints and a bosonic pure spinor variable. This same method was recently used for covariantly quantizing the superstring, and it is hoped that the simpler case of the superparticle will be useful for those who want to study this quantization method. It is interesting ...
متن کاملA New Limit of the AdS 5 × S 5 Sigma Model
Using the pure spinor formalism, a quantizable sigma model has been constructed for the superstring in an AdS5 × S 5 background with manifest PSU(2, 2|4) invariance. The PSU(2, 2|4) metric gAB has both vector components gab and spinor components gαβ, and in the limit where the spinor components gαβ are taken to infinity, the AdS5 × S 5 sigma model reduces to the worldsheet action in a flat back...
متن کاملTowards a Worldsheet Derivation of the Maldacena Conjecture
A U(2, 2|4)-invariant A-model constructed from fermionic superfields has recently been proposed as a sigma model for the superstring onAdS5×S. After explaining the relation of this A-model with the pure spinor formalism, the A-model action is expressed as a gauged linear sigma model. In the zero radius limit, the Coulomb branch of this sigma model is interpreted as D-brane holes which are relat...
متن کاملTESE DE DOUTORAMENTO Superstring Sigma Model Computations Using the Pure Spinor Formalism
In this thesis are presented two aplications of the sigma model for the superstring in the pure spinor formulation. The first aplication concerns the computation of the one-loop conformal invariance for the type II superstring, resulting in equations of motion written in superspace for the background fields coupled to the superstring. The second application is related to the BRST invariance of ...
متن کاملAbsence of higher order corrections to the non-Abelian Chern-Simons coefficient
We extend the Coleman-Hill analysis to non-Abelian Chern-Simons theories containing a tree level topological mass term. We show, in the case of a pure Yang-Mills-Chern-Simons theory, that there are no corrections to the coefficient of the Chern-Simons term beyond one loop in the axial gauge. Our arguments use constraints coming only from small gauge Ward identities as well as the analyticity of...
