摘要

在非相对论势模型中考虑耦合通道效应，研究了粲介子的质谱。对粲介子质量的预测与实验数据一致。利用非相对论势模型的数值波函数进一步分析了P03模型中的强衰减特性。基于预测的质量和衰变性质，我们给出了最近观测到的粲态的分类。特别地，我们通过考虑S - D混合，有效地解释了D1*(2600)和D1*(2760)的质量和衰减特性。此外，所预测的2P波态的质量和衰减性质有助于今后在实验中寻找它们。2025年由美国物理学会出版

Spectrum and decay properties of the charmed mesons involving the coupled channel effects

The mass spectrum of the charmed mesons is investigated by considering the coupled channel effects within the nonrelativistic potential model. The predicted masses of the charmed mesons are in agreement with experimental data. The strong decay properties are further analyzed within the P03 model by using numerical wave functions obtained from the nonrelativistic potential model. Based on the predicted masses and decay properties, we give a classification of the recently observed charmed states. Especially, we have effectively explained the masses and decay properties of the D1*(2600) and D1*(2760) by considering the S−D mixing. Furthermore, the predicted masses and decay properties of the 2P wave states are helpful to search for them experimentally in future.
