摘要
为改善夸克蜕定域色屏蔽模型在长程处的行为 ,在模型中加入了单π交换 ,氘核的计算结果很好地符合了实验 .同时 ,d 的质量和衰变宽度没有明显变化 .这表明 。
The quark-delocalization,color-screening model(QDCSM),extended by inclusion of a one-pion-exchange(OPE)tail,is applied to the study of the deuteron and d dibaryon.The results show that the properties of the deuteron(and extended object) are well reproduced,greatly improving the agreement with experimental data.At the same time,the mass and decay width of the d (a compact object)are,as expected,not altered significantly.
