Strings on type-IIB pp-wave backgrounds with interacting massive theories on the worldsheet
Alin Tirziu1 and Paul Fendley1
Show affiliationsWe consider superstring theories on pp-wave backgrounds which result in an integrable 
= (2,2) supersymmetric Landau-Ginzburg theory on the worldsheet. We obtain exact eigenvalues of the light-cone gauge superstring hamiltonian in the massive and interacting world-sheet theory with superpotential Z3−Z. We find the modes of the supergravity part of the string spectrum, and their space-time interpretation. Because the system is effectively at strong coupling on the worldsheet, these modes are not in one-to-one correspondence with the usual type-IIB supergravity modes in the p−→0 limit. However, the above correspondence holds in the α'→0 limit.
