论文摘要
分析了魅力介子的半衰减衰变宽度的分支比例，使用三种不同的iSgur -Wise功能的模型，例如$ {d^ 0} \ to {k^ - } {l^ +} {l^ +} {l^ +} \ to {k^ 0} {l^ +}ν$和$ {d_s} \ toη{l^ +}ν$，其中讨论了这些衰减的形式。获得魅力介子的质谱。我们使用潜在的夸克模型，并将魅力梅森的非偏见性哈密顿人视为夸克 - 易夸克系统的结合状态。我们考虑了谐波类型的限制以及Hellmann的潜力，这是库仑和Yukawa潜力的叠加。使用变分方法以及谐波振荡器波函数，我们评估了魅力中的质谱，形式因子和$ d _ {（s）} $的半衰减衰减宽度。我们介绍了$ D，D_S $和$η$的质量，ISGUR的功能，半衰减衰减的形式以及半衰减衰减的分支分数为$ d $ and $ d $和$ d_s $。我们的结果是有动力的。
The branching ratios of the semileptonic decay widths of the charm mesons are analyzed, using three different models for the Isgur-Wise functions, such as ${D^0} \to {K^ - }{l^ + }\upsilon $, ${D^0} \to {π^ - }{l^ + }ν$, ${D_s} \to {K^0}{l^ + }ν$ and ${D_s} \to η{l^ + }ν$, where the form factors of these decays are discussed. The mass spectra of the charm mesons are obtained. We use a potential quark model and consider the non-relativistic Hamiltonian of the charm meson as a bound state of the quark-antiquark system. We take into account the harmonic-type confinement and also Hellmann potential, which is a superposition of the Coulomb and the Yukawa potential. Using the variational approach along with the harmonic oscillator wave functions, we evaluate the mass spectra of the charm mesons, the form factors and the semileptonic decay widths of $D_{(s)}$. We present our results for masses of $D, D_s$ and $η$, the Isgur-Wise functions, the form factors of the semileptonic decays, and the branching fractions of the semileptonic decays of $D$ and $D_s$. Our results are motivating.
