The strong decays of experimentally observed excited nonstrange charmed mesons are analyzed in the framework of heavy quark effective theory (HQET). The ratio of the strong decay rates identified the doublets \((D_1(2420), D_2^*(2460))\) as \((1^3P_1, 1^3P_2)\), \((D(2550), D_J^*(2600))\) as \((2^1S_0, 2^3S_1)\) and \((D(2740), D_J^*(2750))\) as \((1^3D_2, 1^3D_3)\). The \(D_J(3000)\) is interpreted as the mixing of \(2^1P_1 - 2^3P_1\) states. The resonances \(D{_{J}^*}(3000)\) and \(D_2^*(3000)\) are identified with \(2^3P_2\) and \(1^3F_2\) quantum states, respectively. Such states allows to construct the Regge trajectories in \((M^2, J)\) and \((M^2, n_r)\) planes. We fix the slope and the intercept of each Regge line and estimate the masses of higher excited nonstrange charmed mesons which are lying on the Regge lines. Also, the ratios of the strong decay rates of this higher excited nonstrange charmed mesons are calculated. It can provide valuable information to future experimental search.

在重夸克有效理论（HQET）的框架下分析了实验观察到的激发的非奇异迷惑介子的强衰变。强衰减率的比率将双峰\（（D_1（2420），D_2 ^ *（2460））\）标识为\（（1 ^ 3P_1，1 ^ 3P_2）\），\（（D（2550）， D_J ^ *（2600））\）如\（（2 ^ 1S_0，2 ^ 3S_1）\）和\（（D（2740），D_J ^ *（2750））\）如\（（1 ^ 3D_2，1 ^ 3D_3）\）。的\（D_J（3000）\）被解释为的混合（2 ^ 1P_1 - 2 ^ 3P_1 \）\状态。谐振\（D {_ {J} ^ *}（3000）\）和\（D_2 ^ *（3000）\）用\（2 ^ 3P_2 \）和\（1 ^ 3F_2 \）标识量子态。这样的状态允许在\（（M ^ 2，J）\）和\（（M ^ 2，n_r）\）平面中构造Regge轨迹。我们固定每个Regge线的斜率和截距，并估算位于Regge线上的更高激发的非奇异魅力介子的质量。同样，计算出这种较高激发的非奇异的有魅力介子的强衰变率之比。它可以为将来的实验搜索提供有价值的信息。
