标题： Mass spectrum of Mesons via the WKB approximation method

摘要： 本文中，我们证明了在 Wentzel-Kramers-Brillouin (WKB) 近似方法框架下的多重转折点问题可以通过使用适当的 Pekeris 型近似方案简化为一个非对称势函数的两个转折点问题。 我们解决了带有 Killingbeck 势和反向二次势（KPIQP）函数的薛定谔方程。 讨论了建模势的特殊情况。 我们得到了重夸克onium系统和重轻夸克onium系统的能级和质量谱。 本工作的结果与其他解析方法以及文献中可用的实验数据非常一致。 显示英文摘要

摘要： In this paper, we demonstrated that the multiple turning point problems within the framework of the Wentzel-Kramers-Brillouin (WKB) approximation method can be reduced to two turning point one for a non-symmetric potential function by using an appropriate Pekeris-type approximation scheme. We solved the Schr\"odinger equation with the Killingbeck potential plus an inversely quadratic potential (KPIQP) function. The special cases of the modeled potential are discussed. We obtained the energy eigenvalues and the mass spectra of the heavy and heavy-light mesons systems. The results in this present work are in good agreement with the results obtained by other analytical methods and available experimental data in the literature
