论文摘要
对双重重子的性质的研究代表了粒子物理学的一个有希望的区域。它可以为我们提供有关Cabibbo-Kobayashi-Maskawa（CKM）矩阵元素和QCD低能动力学的信息。他们有一个非常丰富的现象学。对弱，电磁和较强衰减的研究对于理解双重重型重子的动态至关重要。此类研究的主要成分是光谱参数，强耦合常数和过渡形式。为了计算这些数量，需要非扰动方法。这些方法之一是QCD和规则。在目前的工作中，我们回顾了关于偶有重型重子在总规则方法中的性质的研究，主要集中于偶发重型重子的质量和强耦合常数。此外，使用矢量优势模型估算了双重重气子的辐射衰变。我们还对双重重型重子的半衰减衰减发表了一些评论。
The study of the properties of doubly heavy baryons represents a promising area in particle physics. It can provide us with information about Cabibbo-Kobayashi-Maskawa (CKM) matrix elements and the low energy dynamics of QCD. They have a very rich phenomenology. The investigation of weak, electromagnetic, and strong decays has vital importance for understanding the dynamics of doubly heavy baryons. The main ingredients of such studies are the spectroscopic parameters, the strong coupling constants, and the transition form factors. For calculations of these quantities, non-perturbative methods are needed. One of these methods is the QCD sum rules. In the present work, we review our studies on the properties of the doubly heavy baryons within the sum rules method, focusing mainly on the mass and strong coupling constants of the doubly heavy baryons. In addition, the radiative decays of doubly heavy baryons are estimated using the vector dominance model. We also make few remarks on the semileptonic decays of the doubly heavy baryons.
