X(3872)的^(*0)D^0衰变
^(*0)D^0 Decay of X(3872)
摘要
利用3 P0衰变模型对X(3872)的*0D0衰变宽度进行了计算和分析.计算结果表明,将X(3872)视为1++粲偶素时得到的衰变宽度与实验结果以及其它理论模型得到的计算结果一致.这对进一步理解X(3872)的特性提供有益的帮助.
The D* 0D0 decay of X(3872) are investigated in the 3 Po decay model. We find that the predicted decay widths of the X(3872) can agree with the experimental data and other theoretical approaches,when X(3872) is assigned as a 1++ char- monium. The calculation will be helpful for the further understanding of X(3872).
