A note on string interaction on the pp-wave background.

Chu, C. S. and Khoze, V. V. and Petrini, M. and Russo, R. and Tanzini, A. (2004) 'A note on string interaction on the pp-wave background.', Classical and quantum gravity., 21 (8). pp. 1999-2009.


We consider type IIB string interaction on the maximally supersymmetric pp-wave background and discuss how the bosonic symmetries of the background are realized. This analysis shows that there are some interesting differences with respect to the flat-space case and suggests modifications to the existing form of the string vertex. We focus on the zero-mode part which is responsible for some puzzling string predictions about the super Yang–Mills side. We show that these puzzles disappear when a symmetry preserving string interaction is used.
