轻玻色子可以在标准模型之外的一大类理论中找到。目前的实验可能无法排除这些轻玻色子的存在，甚至可能为一些异常的实验结果提供解释。夸克素 (cc, bb) 态的辐射衰变为研究此类轻玻色子提供了一个有希望的机会。具体来说，我们研究了当前 CLEO 数据在光标量和赝标量玻色子模型上的影响范围。
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 (cc, bb) 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.
