摘要:

我们描述了一种解析方法,通过该方法,散射振幅可直接从输入的质量谱和若干物理约束中自举得到,这些约束包括交叉对称性、高能下的有界性以及交换自旋的有限性。对于整数谱,该程序从第一性原理出发推导出Veneziano振幅的一个新的无穷参数推广,该推广具有幺正性,同时表现出对偶共振和一致的高能行为。提升到q变形的整数谱,我们推导出Coon振幅及其类似的推广。最后,我们将这一逻辑应用于推导一类无穷多的变形Virasoro-Shapiro振幅。

英文摘要:

We describe an analytic procedure whereby scattering amplitudes are bootstrapped directly from an input mass spectrum and a handful of physical constraints: crossing symmetry, boundedness at high energies, and finiteness of exchanged spins. For an integer spectrum, this procedure gives a first principles derivation of a new infinite parameter generalization of the Veneziano amplitude that is unitary while exhibiting dual resonance and consistent high-energy behavior. Lifting to a $q$-deformed integer spectrum, we derive the Coon amplitude and its analogous generalizations. Finally, we apply this logic to derive an infinite class of deformed Virasoro-Shapiro amplitudes.
