论文摘要
我们描述了一个通用框架，以描述洛伦兹不变的有效田野理论的空间，我们称之为景观，鉴于任何类型的规格对称性和田间内容。景观中的各种操作员群可以在振幅操作员对应关系的帮助下系统地构建，以强调不同的方面：操作员独立性（Y-BASIS），风味关系（P-BASIS）（P-BASIS）和保守的量子数（J-Basis）。碱基之间的转换矩阵编码操作员的模型无关属性，例如对其紫外线的影响。我们在检查与中子抗抗振荡相关的尺寸9操作员时说明了这一显着特征。
We describe a general framework to depict the space of Lorentz invariant effective field theories, which we call the landscape, given any kind of gauge symmetry and field content. Various operator bases in the landscape can be systematically constructed, with the help of amplitude-operator correspondence, to emphasize different aspects: operator independence (y-basis), flavor relation (p-basis) and conserved quantum number (j-basis). The transformation matrices among the bases encode model-independent properties of the operators, such as implications on their UV origin. We illustrate this salient feature in examining the dimension 9 operators relevant for neutron-antineutron oscillation.
