论文摘要

本文介绍了两个当前非常活跃的研究计划,即保形引导和散射幅度。与其尝试进行全面调查,不如说是这两个看似截然不同的程序共享的共同思想和方法。在这两个领域中,数学和物理约束都直接放在物理观察物上,以探索可能一致的量子场理论的景观。我们从两个程序中给出了明确的例子:读者可以期望在这一范围内进入当地相对论量子场理论的景观的旅程中遇到沸水,铁磁体,触发散射和新兴的对称性。第一部分是为一般物理观众编写的。第二部分包括更多详细信息,包括$ \ mathbb {cp}^1 $模型的新壳上自下而上的重建,该重建是由fubini-study度量的,这是由$ n $ point交互术语重新固定而产生的。

This article is an introduction to two currently very active research programs, the Conformal Bootstrap and Scattering Amplitudes. Rather than attempting full surveys, the emphasis is on common ideas and methods shared by these two seemingly very different programs. In both fields, mathematical and physical constraints are placed directly on the physical observables in order to explore the landscape of possible consistent quantum field theories. We give explicit examples from both programs: the reader can expect to encounter boiling water, ferromagnets, pion scattering, and emergent symmetries on this journey into the landscape of local relativistic quantum field theories. The first part is written for a general physics audience. The second part includes further details, including a new on-shell bottom-up reconstruction of the $\mathbb{CP}^1$ model with the Fubini-Study metric arising from re-summation of the $n$-point interaction terms derived from amplitudes.
