Carrollian holography is supposed to describe gravity in four-dimensional asymptotically flat space-time by the three-dimensional Carrollian CFT living at null infinity. We transform superstring scattering amplitudes into the correlation functions of primary fields of Carrollian CFT depending on the three-dimensional coordinates of the celestial sphere and a retarded time coordinate. The power series in the inverse string tension is converted to a whole tower of both UV and IR finite descendants of the underlying field-theoretical Carrollian amplitude. We focus on four-point amplitudes involving gauge bosons and gravitons in type I open superstring theory and in closed heterotic superstring theory at the tree-level. We also discuss the limit of infinite retarded time coordinates, where the string world-sheet becomes celestial.

卡罗尔全息术应该通过生活在零无穷远的三维卡罗尔 CFT 来描述四维渐近平坦时空中的引力。我们根据天球的三维坐标和延迟时间坐标将超弦散射振幅转换为卡罗尔 CFT 主场的相关函数。逆弦张力的幂级数被转换为基础场论卡罗尔振幅的紫外和红外有限后代的整个塔。我们重点关注树级 I 型开放超弦理论和封闭异质超弦理论中涉及规范玻色子和引力子的四点振幅。我们还讨论了无限延迟时间坐标的限制，其中弦世界表变成天体。
