Plane-wave lightcone superstring field theory
We construct the cubic interaction vertex and dynamically generated supercharges in lightcone superstring field theory for a large class half-supersymmetric D-branes in the planewave background. We show that these satisfy the plane-wave superalgebra at first order in string coupling. The cubic interaction vertex and dynamical supercharges presented here are given explicitly in terms of oscilators and can be used to compute three-point functions of open strings with endpoints on half-supersymmetric D-branes
The 3-string vertex and the AdS/CFT duality in the PP-wave limit
We pursue the study of string interactions in the PP-wave background and show
that the proposal of hep-th/0211188 can be extended to a full supersymmetric
vertex. Then we compute some string amplitudes in both the bosonic and
fermionic sector, finding agreement with the field theory results at leading
order in lambda'.Comment: Latex, 25 pages. Comments added and typos correcte
The Duality between IIB String Theory on PP-wave and N=4 SYM: a Status Report
The aim of this report is to give an overview of the duality between type IIB
string theory on the maximally supersymmetric PP-wave and the BMN sector of N=4
Super Yang-Mills theory. The general features of the string and the field
theory descriptions are reviewed, but the main focus of this report is on the
comparison between the two sides of the duality. In particular, it is first
explained how free IIB strings emerge on the gauge theory side and then the
generalizations of this relation to the full interacting theory are considered.
An ``historical'' approach is taken and the various proposals presented in the
literature are described.Comment: 35 pages, 5 figures; Contribution to the proceedings of the

String interactions and discrete symmetries of the pp-wave background
Free string theory on the plane-wave background displays a discrete Z2
symmetry exchanging the two transverse SO(4) rotation groups. This symmetry
should be respected also at the interacting level. We show that the zero mode
structure proposed in hep-th/0208148 can be completed to a full kinematical
vertex, contrary to claims appeared in the previous literature. We also comment
on the relation with recent works on the string-bit formalism and on the
comparison with the field theory side of the correspondence.Comment: Proceeding of the 35th Symposium Ahrenshoop Aug 2002 and the Leuven
