具有美的重子和介子

Baryons and Mesons with Beauty

Gary R. Goldstein, Kameshwar C. Wali

摘要:

最近几个介子和重子的实验发现与“美丽”和“魅力”的味道提醒我们的日子,当奇怪的发现,以及它的纳入如何导致SU(3)-味对称性的巨大成功分类的“增殖”状态到SU(3)多重态。其中一个关键因素是成功地应用了一阶微扰对称破缺,尽管当时似乎存在巨大的质量差异,并预测了新的状态,并得到了实验的证实。在这篇笔记中,我们冒险进入过去,并应用相同的技术,预测一些新的“美丽”和“魅力”口味的强子。如果这些新的状态被实验证实,它可能会提供一个有用的唯象模型,用于对PDG数据中发现的许多状态进行分类,并可能对我们理解对称性破缺提出进一步的理论挑战。

英文摘要:

Recent experimental findings of several mesons and baryons with "beauty" and "charm" as flavors remind us of the days when strangeness was discovered, and how its inclusion led to SU(3)-flavor symmetry with enormous success in the classification of the "proliferated" states into SU(3) multiplets. One of the key elements was the successful application of the first order perturbation in symmetry breaking, albeit what then appeared to be huge mass differences, and the prediction of new states that were confirmed by experiments. In this note, we venture into the past and, applying the same techniques, predict some new "beauty-" and "charm-" flavored hadrons. If these new states are confirmed experimentally, it may provide a useful phenomenological model for classifying numerous states that are found to be in the PDG data and could invite further theoretical challenges towards our understanding of symmetry breaking.
