论文摘要
在目前的工作中，我们对修改的相对论夸克模型中诱人的介子的辐射衰变进行系统估计。我们的估计表明，$ d_2^0（1^3p_2）\到d^{\ ast 0}（1^3S_1）γ$，$ d_3^0（1d_3）\ to d_2^0（1^3p_2）γ$，$ d_2^0（prime） d_1^{0}（2p_1）γ$，$ d_3^0（2^3d_3）\ to d_2^0（2^3p_2）γ$，和$ d^{\ ast 0}（1^3s_1）实验。此外，某些频道的分支比率，例如$ d_1^0（1p_1）\ to d（1^1s_0）^0γ$，$ d^0（3^1s_0）\ to d_1^{\ prime 0}（2p^\ prime_ {1}） d_2^0（2^3p_2）γ$估计为$ 10^{ - 3} $的顺序，在将来的实验中，数据的积累可以访问。
In the present work, we perform systematic estimations for the radiative decays of the charmed mesons in a modified relativistic quark model. Our estimations indicate that the branching ratios of the process of $D_2^0(1^3P_2) \to D^{\ast 0}(1^3S_1) γ$, $D_3^0(1D_3) \to D_2^0(1^3P_2) γ$, $D_2^0(2D_2^\prime) \to D_1^{0}(2P_1) γ$, $D_3^0(2^3D_3) \to D_2^0(2^3P_2) γ$, and $D^{\ast 0}(1^3S_1) \to D^0(1^1S_0) γ$ are of the order of $10^{-2}$, which are sizable to be detected experimentally. Moreover, the branching ratios of some channels, for example, $D_1^0(1P_1) \to D(1^1S_0)^0 γ$, $D^0(3^1S_0) \to D_1^{\prime 0}(2P^\prime_{1}) γ$ and $D^0(3^3S_1) \to D_2^0(2^3P_2) γ$ are estimated to be of the order of $10^{-3}$, which may be accessible with the accumulation of data in future experiments.
