标题： Hadron loops effect on mass shifts of the charmed and charmed-strange spectra

摘要： 强子环效应被认为在理解实验中观察到的状态与非相对论势模型理论预期之间的差异中起着重要作用。 我们提出，在一个易于操作的程序中，强子环效应可以将极点向下移动，以减小差异，并对径向量子数$n=1$的 charm 和 charm-Strange 状态的质量和总宽度提供更好的描述。 由于它们与共同通道的耦合，$1^1P_1-1^3P_1$的混合现象可以自然地得到解释。 新观测到的$D$状态也得到了讨论，但仍然存在一些问题尚未明确。 显示英文摘要

摘要： The hadron loop effect is conjectured to be important in understanding discrepancies between the observed states in experiments and the theoretical expectations of non-relativistic potential model. We present that, in an easily operable procedure, the hadron loop effect could shift the poles downwards to reduce the differences and provide better descriptions of both the masses and the total widths, at least, of the radial quantum number $n=1$ charmed and charmed-strange states. The $1^1P_1-1^3P_1$ mixing phenomena could be naturally explained due to their couplings with common channels. The newly observed $D$ states are also addressed, but there are still some problems remaining unclear.
