摘要

我们证明弦理论的威尼斯振幅是可分析求解的自举问题的唯一解。唯一性源于两个假设：高能散射的幂律衰减比幂律衰减快，以及动量传递中存在某个无限序列，在该序列上高自旋交换抵消。弦振幅--包括质量谱--是这一引导的输出。如果振幅只是在高能量下消失，那么解就是一个三参数族，包含维尼切诺振幅、库恩振幅和超几何振幅等。美国物理学会出版 2024

Bootstrap Principle for the Spectrum and Scattering of Strings

We show that the Veneziano amplitude of string theory is the unique solution to an analytically solvable bootstrap problem. Uniqueness follows from two assumptions: faster than power-law falloff in high-energy scattering and the existence of some infinite sequence in momentum transfer at which higher-spin exchanges cancel. The string amplitude—including the mass spectrum—is an output of this bootstrap. If the amplitude merely vanishes at high energies, the solution is a three-parameter family containing the Veneziano, Coon, and hypergeometric amplitudes, and more.
