本文提出了一个协变闭合超弦场论，它等价于经典的张维II型超引力。共形场理论的定义是Mason和Skinner的ambitwistor弦世界页理论。这一理论重现了Cachazo、He和袁的散射幅度，其中散射方程起着重要作用，弦场理论自然地结合了这些结果。我们研究了有界弦的算符形式描述，并提出了它对玻色理论和超对称理论中弦场论的作用。明确地再现了正确的线性化规范对称性和时空作用量，并给出了该作用量对所有阶数都是正确的证据。重点讨论了奈威-施瓦茨部门和关于平坦时空的树级微扰理论的显式描述。简要讨论了弦场理论在一般超重力背景中的应用以及Ramond扇区的包含。
A bstractA covariant closed superstring field theory, equivalent to classical tendimensional Type II supergravity, is presented. The defining conformal field theory is the ambitwistor string worldsheet theory of Mason and Skinner. This theory is known to reproduce the scattering amplitudes of Cachazo, He and Yuan in which the scattering equations play an important role and the string field theory naturally incorporates these results. We investigate the operator formalism description of the ambitwsitor string and propose an action for the string field theory of the bosonic and supersymmetric theories. The correct linearised gauge symmetries and spacetime actions are explicitly reproduced and evidence is given that the action is correct to all orders. The focus is on the NeveuSchwarz sector and the explicit description of tree level perturbation theory about flat spacetime. Application of the string field theory to general supergravity backgrounds and the inclusion of the Ramond sector are briefly discussed.
