On semiclassical analysis of pure spinor superstring in an AdS_5 x S^5 background
Yuri Aisaka, L. Ibiapina Bevilaqua, Brenno C. Vallilo
Relation between semiclassical analyses of Green-Schwarz and pure spinor formalisms in an AdS_5 x S^5 background is clarified. It is shown that the two formalisms have identical se…
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…
Hilbert space of curved βγsystems on quadric cones
Yuri Aisaka, E. Aldo Arroyo
We clarify the structure of the Hilbert space of curved βγsystems defined by a quadratic constraint. The constraint is studied using intrinsic and BRST methods, and their partition…
Pure Spinor Partition Function and the Massive Superstring Spectrum
Yuri Aisaka, E. Aldo Arroyo, Nathan Berkovits +1
We explicitly compute up to the fifth mass-level the partition function of ten-dimensional pure spinor worldsheet variables including the spin dependence. After adding the contribu…
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…
Origin of Pure Spinor Superstring
Yuri Aisaka, Yoichi Kazama
The pure spinor formalism for the superstring, initiated by N. Berkovits, is derived at the fully quantum level starting from a fundamental reparametrization invariant and super-Po…
