运用弦模型研究含有粲夸克的D介子谱.通过引入自旋自旋以及自旋轨道相互作用,发现D介子谱能被很好的描述.当把这个模型用于奇异Ds介子谱时,预测存在质量为2516 MeV的第一轨道激发态粒子.文章还分析了这类相互作用在单粲夸克重子谱中对能级劈裂的贡献.

Using a relativistic string model,the charmed D meson spectrum has been studied.The spectrum can well be depicted by including spin-spin and spin-orbital interactions.First orbital excited meson with mass 2516 MeV has been predicted in Ds spectrum by using this model.Furthermore,The manifestations of S-S and S-L interactions in the charmed baryon spectrums have also been discussed.
