论文摘要
字符串 - 本地场构成了一个相对较新的工具，用于解决量子场理论，强调和体现局部性和积极性。我们在这里检查了它们的有用性 - 以及一些缺点。从仅仅是已知粒子的物理质量和电荷开始，并在Bogoliubov-Epstein-Glaser（BEG）理论框架中带来弦独立性，被视为发现的手段，人们发现与这些粒子相关的量子字段允许的耦合，从而无需恢复所有标准模型（SM）而无需恢复了所有的调用。结果之一是要求该田地由还原的代数支配。另一个是至少需要一个标量粒子。另一个是由大颗粒介导的相互作用的手性。此表述中没有空间作为``全球''仪表不变性作为先验构造。用这种现代武器配备了这种现代武器，我们在这里重新评估了一些古典和近期的Conundra。特别是，我们从采用弦 - 本地领域的宇宙学角度研究了新的观点。
String-local fields constitute a relatively new tool for solving quantum field theory, stressing and embodying locality and positivity. We examine here their usefulness -- as well as some drawbacks. Starting from just the physical masses and charges of the known particles, and bringing string independence in the Bogoliubov-Epstein-Glaser (BEG) theory framework, regarded as a means of discovery, one finds the allowed couplings of quantum fields associated to those particles, and thereby recovers all of the Standard Model (SM) without invoking theoretical prejudices. One of the outcomes is the requirement that the fields be governed by reductive Lie algebras. Another is the need for at least one scalar particle. Yet another is chirality of interactions mediated by massive particles. There is no room in this formulation for ``global'' gauge invariance as an a priori construct. Armed with this modern weapon, we reassess here a few classical and recent conundra. In particular, we examine new perspectives in cosmology from the adoption of string-local fields.
