A Worldsheet Theory for Supergravity

Understand

We present a worldsheet theory that describes maps into a curved target space equipped with a B-field and dilaton.

• The conditions for the theory to be consistent at the quantum level can be computed exactly, and are that the target space fields obey the nonlinear d=10 supergravity equations of motion, with no higher curvature terms.
• The path integral is constrained to obey a generalization of the scattering equations to curved space.
• Remarkably, the supergravity field equations emerge as quantum corrections to these curved space scattering equations.
