超引力的世界表理论

A Worldsheet Theory for Supergravity

Tim Adamo, Eduardo Casali, David Skinner

摘要:

我们提出了一个世界片理论,它描述了一个弯曲的目标空间配备了一个B-场和drons的地图。理论在量子水平上是一致的条件可以精确计算,并且目标空间场服从非线性d=10的超引力运动方程,没有更高的曲率项。路径积分被约束为服从散射方程到弯曲空间的推广。值得注意的是,超引力场方程是对这些弯曲的空间散射方程的量子修正。

英文摘要:

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.
