On D-Brane Boundary State Analysis in Pure Spinor Formalism
We explore a particular approach to study D-brane boundary states in Berkovits’ pure spinor formalism of superstring theories. In this approach one constructs the boundary states in the relevant conformal field theory by relaxing the pure spinor constraints. This enables us to write down the open string boundary conditions for non-BPS D-branes in type II string theories, generalizing our previo...
متن کاملCovariant Matrix Model of Superparticle in the Pure Spinor Formalism
On the basis of the Berkovits pure spinor formalism of covariant quantization of supermembrane, we attempt to construct a M(atrix) theory which is covariant under SO(1, 10) Lorentz group. We first construct a bosonic M(atrix) theory by starting with the first-order formalism of bosonic membrane, which precisely gives us a bosonic sector of M(atrix) theory by BFSS. Next we generalize this method...
متن کاملPure Spinor Formalism for Conformal Fermion and Conserved Currents
Pure spinor formalism and non-integrable exponential factors are used for constructing the conformal-invariant wave equation and Lagrangian density for massive fermion. It is proved that canonical Dirac Lagrangian for massive fermion is invariant under induced projective conformal transformations.
متن کاملSimplifying and Extending the AdS5 × S Pure Spinor Formalism
Although the AdS5×S worldsheet action is not quadratic, some features of the pure spinor formalism are simpler in an AdS5 × S background than in a flat background. The BRST operator acts geometrically, the left and right-moving pure spinor ghosts can be treated as complex conjugates, the zero mode measure factor is trivial, and the b ghost does not require non-minimal fields. Furthermore, a top...
متن کاملY-formalism in Pure Spinor Quantization of Superstrings
We present the Y-formalism in the pure spinor quantization of superstring theory in detail. Even if the ω−λ OPE is not completely free owing to the presence of the projector reflecting the pure spinor constraint, it is shown that one can construct at the quantum level a conformal field theory in full agreement with the Berkovits’ pure spinor formalism. The OPE’s of the two formalisms are the sa...
