摘要：

2008年，Aharony、Bergman、Jafferis和Maldacena（ABJM）发现了一个N = 6的三维Chern-Simons理论，并证明在一定的极限下，这个理论与AdS 4xCP 3上的IIA型弦论是对偶的。从那时起，已经积累了大量的证据表明，ABJM理论是可积的平面极限。可积性是一个非常有用的性质，它允许许多物理观测量，如反常维数和散射振幅，被有效地计算。在本文的前半部分，我们将解释如何利用可积性来计算ABJM理论中长单迹算子的反常维数。特别地，我们将描述如何在弱耦合下用贝特算符计算它们，以及如何在强耦合下用弦论计算它们。后一种方法涉及使用代数曲线和世界片技术来计算弦态的能量对偶规范理论运营商。在本文的后半部分，我们将从ABJM理论中壳层上散射振幅的角度讨论可积性。特别是，我们将描述如何参数化的振幅在supertwistors和如何相关的高点树级振幅较低点树级振幅使用递归关系。我们还将解释如何使用这种递归关系来证明ABJM理论的所有树能级振幅在对偶超共形对称下是不变的。这种对称性从作用点来看是隐藏的，这意味着该理论具有杨氏对称性，这是可积性的一个关键特征。本文主要是在文献[101]、[83]、[84]的基础上进行的。

英文摘要：

In 2008, Aharony, Bergman, Jafferis, and Maldacena (ABJM) discovered a three-dimensional Chern-Simons theory with N = 6 supersymmetry and conjectured that in a certain limit, this theory is dual to type IIA string theory on AdS4xCP3. Since then, a great deal of evidence has been accumulated which suggests that the ABJM theory is integrable in the planar limit. Integrability is a very useful property that allows many physical observables, such as anomalous dimensions and scattering amplitudes, to be computed efficiently. In the first half of this thesis, we will explain how to use integrabilty to compute the anomalous dimensions of long, single-trace operators in the ABJM theory. In particular, we will describe how to compute them at weak coupling using a Bethe Ansatz, and how to compute them at strong coupling using string theory. The latter approach involves using algebraic curve and world-sheet techniques to compute the energies of string states dual to gauge theory operators. In the second half of this thesis, we will discuss integrability from the point of view of on-shell scattering amplitudes in the ABJM theory. In particular, we will describe how to parameterize the amplitudes in terms of supertwistors and how to relate higher-point tree-level amplitudes to lower-point tree-level amplitudes using a recursion relation. We will also explain how this recursion relation can be used to show that all tree-level amplitudes of the ABJM theory are invariant under dual superconformal symmetry. This symmetry is hidden from the point of the action and implies that the theory has Yangian symmetry, which is a key feature of integrability. This thesis is mainly based on the material in [101], [83], and [84].
