PP-Wave Light-Cone Superstring Field Theory
We construct the cubic interaction vertex and dynamically generated supercharges in light-cone superstring field theory in the pp-wave background. We show that these satisfy the pp-wave superalgebra at first order in string coupling. The cubic interaction vertex and dynamical supercharges presented here differ from the expressions previously given in the literature. Using this vertex we compute...
متن کاملSuperstring Interactions in a pp-wave Background
We construct light-cone gauge superstring field theory in a pp-wave background with Ramond-Ramond flux. The leading term in the interaction Hamiltonian is determined up to an overall function of p by requiring closure of the pp-wave superalgebra. The bosonic and fermionic Neumann matrices for this cubic vertex are derived, as is the interaction point operator. We comment on the development of a...
متن کاملSuperstring in the pp - wave background with RR flux as a conformal field theory ∗
We provide a concise description of our recent work on the exact conformal field theory ( CFT) formulation of the superstring in the pp-wave background with Ramond-Ramond (RR) flux, using the Green-Schwarz formalism in the semi-light-cone conformal gauge. Due to the presence of the RR flux, the leftand the right-moving degrees of freedom on the worldsheet are inherently coupled and this makes t...
متن کاملMore comments on superstring interactions in the pp-wave background
We reconsider light-cone superstring field theory on the maximally supersymmetric pp-wave background. We find that the results for the fermionic Neumann matrices given so far in the literature are incomplete and verify our expressions by relating them to the bosonic Neumann matrices and proving several non-trivial consistency conditions among them, as for example the generalization of a flat sp...
متن کاملSuperstring Interactions in a pp-wave Background II
In type IIB light-cone superstring field theory, the cubic interaction has two pieces: a delta-functional overlap and an operator inserted at the interaction point. In this paper we extend our earlier work hep-th/0204146 by computing the matrix elements of this operator in the oscillator basis of pp-wave string theory for all μp+α′. By evaluating these matrix elements for large μp+α′, we provid...
