标题： Anatomy of Parity-violating Trispectra in Galaxy Surveys

摘要： 在粒子物理中，破坏宇称的相互作用是普遍现象。如果在宇宙暴胀期间它们很重要，它们会在原初扰动上留下痕迹，并在星系调查的相关函数中被观测到。重要的是，在大尺度上，四点相关函数（4PCFs）中的宇称破坏信号无法由晚时期的爱因斯坦引力产生，这使它们成为暴胀期间高能物理的独特而有力的探针。然而，4PCF的复杂结构给从观测数据中诊断宇称破坏相互作用的潜在特性带来了挑战。在这项工作中，我们引入了一个通用框架，该框架提供了一条直接从暴胀中的粒子模型到位置空间中星系4PCFs的简化流程。我们通过一系列玩具模型、类似有效场论的模型以及具有树级交换型过程且具有化学势诱导的宇称破坏的完整模型来演示这个框架。我们进一步展示了这些模型从BOSS数据中的检测灵敏度，并强调了数据解释和模型预测中的潜在挑战。 显示英文摘要

摘要： Parity-violating interactions are ubiquitous phenomena in particle physics. If they are significant during cosmic inflation, they can leave imprints on primordial perturbations and be observed in correlation functions of galaxy surveys. Importantly, parity-violating signals in the four-point correlation functions (4PCFs) cannot be generated by Einstein gravity in the late universe on large scales, making them unique and powerful probes of high-energy physics during inflation. However, the complex structure of the 4PCF poses challenges in diagnosing the underlying properties of parity-violating interactions from observational data. In this work, we introduce a general framework that provides a streamlined pipeline directly from a particle model in inflation to galaxy 4PCFs in position space. We demonstrate this framework with a series of toy models, effective-field-theory-like models, and full models featuring tree-level exchange-type processes with chemical-potential-induced parity violation. We further showed the detection sensitivity of these models from BOSS data and highlighted potential challenges in data interpretation and model prediction.
