用变分方法计算具有双圈静电势的重轻介子的质量

Masses of Heavy-Light mesons with two loop static potential in a Variational approach

Jugal Lahkar, Rashidul Hoque, D. K. Choudhury

摘要:

在本文中,我们用变分法研究了静态Cornell势中几种重轻介子的质量,并考虑了双圈效应。具体来说,我们考虑两个波函数,高斯和库仑。我们的分析表明,这种方法在重味介子区比定态微扰理论和其他近似方法更成功。

英文摘要:

In this work, we investigate the masses of a few heavy-light mesons with variational method, taking into account the two-loop effects in the static Cornell potential. Specifically, we consider two wave-function,Gaussian and Coulomb. Our analysis suggests that phenomenologically such approach is more successful in the Heavy flavoured meson sector than the stationary state perturbation theory and other approximation methods.
