# Nonrelativistic closed string theory

@article{Gomis2001NonrelativisticCS, title={Nonrelativistic closed string theory}, author={Jaume Gomis and Hirosi Ooguri}, journal={Journal of Mathematical Physics}, year={2001}, volume={42}, pages={3127-3151} }

We construct a Galilean invariant nongravitational closed string theory whose excitations satisfy a nonrelativistic dispersion relation. This theory can be obtained by taking a consistent low energy limit of any of the conventional string theories, including the heterotic string. We give a finite first order worldsheet Hamiltonian for this theory and show that this string theory has a sensible perturbative expansion, interesting high energy behavior of scattering amplitudes and a Hagedorn… Expand
