标题： Symmetry-protected conservation of superhorizon inflationary perturbations to all loops

摘要： 我们证明了单场暴胀场系统表现出一种对称性，该对称性通过Ward恒等式约束其演化，即使对于非吸引子暴胀也是如此。 通过分析环图结构，我们直接得出了一个与曲率扰动的两点关联函数相关的超horizon守恒量，将之前的一步结果推广到任意环阶。 这种基于对称性的方法为理解超越主导微扰阶的量子守恒定律提供了框架。 显示英文摘要

摘要： We demonstrates that the single-field inflation field system exhibits a symmetry that constrains its evolution via the Ward identity even for non-attractor inflation. By analyzing loop diagram structures, we derive a superhorizon conserved quantity directly related to the two-point correlation function of curvature perturbations, generalizing previous one-loop results to arbitrary loop orders. This symmetry-based approach provides a framework for understanding quantum conservation laws beyond the leading perturbative order.
