Pure Spinor Vertex Operators in Siegel Gauge and Loop Amplitude Regularization

Yuri Aisaka, Nathan Berkovits

Since the b ghost in the pure spinor formalism is a composite operator depending on non-minimal variables, it is not trivial to impose the Siegel gauge condition b_0 V=0 on BRST-in…

Towards Pure Spinor Type Covariant Description of Supermembrane -- An Approach from the Double Spinor Formalism --

Yuri Aisaka, Yoichi Kazama

In a previous work, we have constructed a reparametrization invariant worldsheet action from which one can derive the super-Poincare covariant pure spinor formalism for the superst…

Relating Green-Schwarz and Extended Pure Spinor Formalisms by Similarity Transformation

Yuri Aisaka, Yoichi Kazama

In order to gain deeper understanding of pure-spinor-based formalisms of superstring, an explicit similarity transformation is constructed which provides operator mapping between t…

Operator Mapping between RNS and Extended Pure Spinor Formalisms for Superstring

Yuri Aisaka, Yoichi Kazama

An explicit operator mapping in the form of a similarity transformation is constructed between the RNS formalism and an extension of the pure spinor formalism (to be called EPS for…

A New First Class Algebra, Homological Perturbation and Extension of Pure Spinor Formalism for Superstring

Yuri Aisaka, Yoichi Kazama

Based on a novel first class algebra, we develop an extension of the pure spinor (PS) formalism of Berkovits, in which the PS constraints are removed. By using the homological pert…
