Generalized temperature and anisotropy dependent Debye screening mass is introduced into the real part of a potential in an anisotropic plasma. The N-radial Schrödinger equation (SE) is approximately solved by using the Nikiforov–Uvarov (NU) method which based on the expansion of power series. Binding energies and dissociation temperatures of charmonium and bottomonium are calculated. In addition, we have calculated the screening mass values for different parameters. Comparing to their values in an isotropic medium, the charmonium and bottomonium binding energies within an anisotropic medium are found to be increased. Also, the dissociation temperatures of both the charmonium and the bottomonium within anisotropic environments appear larger relative to those found within an isotropic medium. Finally, one observes that in any medium the bottomonium dissociation temperature is higher than the charmonium one.

在广义德拜屏蔽质量和 Nikiforov-Uvarov 方法存在下,在各向异性热 QCD 介质中的夸昆熔化

广义温度和各向异性相关的德拜屏蔽质量被引入到各向异性等离子体中电势的实部。N-径向薛定谔方程(SE)是通过使用基于幂级数展开的Nikiforov-Uvarov(NU)方法近似求解的。计算了charmonium和bottonium的结合能和解离温度。此外,我们计算了不同参数的筛选质量值。与它们在各向同性介质中的值相比,发现各向异性介质中的charmonium 和bottonium 结合能增加了。此外,与在各向同性介质中发现的温度相比,各向异性环境中的charmonium 和bottonium 的解离温度似乎更大。最后,
