最小味道违反及超越:短距离动力学的味道代码

Minimal flavour violation and beyond: Towards a flavour code for short distance dynamics

Andrzej J. Buras

摘要:

这十年应该提供了新物理学(NP)的第一个明确的信号,超越了标准模型(SM),这些讲座的目标是在过去十年中流行的SM的各种扩展中回顾风味物理学。经过一个序曲,两个试点部分和结构的味道违反和CP破坏在SM的简要总结,我们将提出弱衰变的理论框架,这将使我们能够区分不同的NP方案。随后,我们将提出12个具体的BSM模型,总结每个模型的味道违反特征的模式。除了最小味违反(MFV)伴随着味盲阶段的模型,我们将讨论一些扩展包含非MFV源的味道和CP破坏,特别是,新的本地运营商起源于右手带电电流和标量电流。接下来,我们将讨论从SM的角度来看数据中的各种异常,这些异常在SM的某些扩展中显得非常自然。在这次演讲中,这一领域的超级明星将发挥非常重要的作用。这些是对NP效应非常敏感的过程,并且理论上是清洁的。特别强调的是各种可观测量之间的相关性,可以让我们区分各种NP场景。有了这些知识,我们将提出一个3*3矩阵形式的编码系统,它有助于区分SM的各种扩展。找到自然选择的味道代码将是迈向味道基本理论的重要一步。我们给出了几个代表特定模型的味道代码的例子。

英文摘要:

This decade should provide the first definitive signals of New Physics (NP) beyond the Standard Model (SM) and the goal of these lectures is a review of flavour physics in various extensions of the SM that have been popular in the last ten years. After an overture, two pilot sections and a brief summary of the structure of flavour violation and CP violation in the SM, we will present the theoretical framework for weak decays that will allow us to distinguish between different NP scenarios. Subsequently we will present twelve concrete BSM models summarizing the patterns of flavour violation characteristic for each model. In addition to models with minimal flavour violation (MFV) accompanied by flavour blind phases we will discuss a number of extensions containing non-MFV sources of flavour and CP violation and, in particular, new local operators originating in right-handed charged currents and scalar currents. Next we will address various anomalies in the data as seen from the point of view of the SM that appear very natural in certain extensions of the SM. In this presentation selected superstars of this field will play a very important role. These are processes that are very sensitive to NP effects and which are theoretically clean. Particular emphasis will be put on correlations between various observables that could allow us to distinguish between various NP scenarios. Armed with this knowledge we will propose a coding system in a form of a 3*3 matrix which helps to distinguish between various extensions of the SM. Finding which flavour code is chosen by nature would be an important step towards the fundamental theory of flavour. We give several examples of flavour codes representing specific models.
