用辐射$Υ(1S)$衰变约束轻玻色子

Constraining Light Bosons with Radiative $Υ(1S)$ Decays

David McKeen

摘要:

轻玻色子可以在标准模型之外的大类理论中找到。这些轻玻色子可能不会被当前的实验排除,甚至可能为一些异常的实验结果提供解释。夸克偶素($c \bar c, b \bar b$)态的辐射衰变为研究这类轻玻色子提供了一个很好的机会。具体来说,我们调查的范围,目前的CLEO数据可以有轻标量和赝标量玻色子模型。

英文摘要:

Light bosons can be found in large classes of theories beyond the Standard Model. These light bosons may not be ruled out by current experiments and, indeed, may even provide an explanation for some anomalous experimental results. The radiative decays of quarkonium ($c \bar c, b \bar b$) states offer a promising opportunity to investigate such light bosons. Specifically, we investigate the reach that current CLEO data can have on models with light scalar and pseudoscalar bosons.
