由pNRQCD的一般特性激发的$B_c$介子谱

$B_c$ meson spectroscopy motivated by general features of pNRQCD

Raghav Chaturvedi, Ajay Kumar Rai

摘要:

本文计算了基态和径向激发态$B_c$介子的质量谱、衰变常数、弱衰变宽度、寿命、分支比和电磁跃迁宽度。为了计算上述性质的薛定谔方程已数值求解的潜力。所采用的潜在的pNRQCD框架中的相对论修正,添加到康奈尔潜力。计算结果与现有的实验和理论结果进行了比较。

英文摘要:

In the present article the mass spectrum, decay constant, weak decay widths, life time and branching fraction ratios and electromagnetic transition widths are calculated for ground and radially excited $B_c$ meson. To calculate the above properties the Schrödinger equation has been solved numerically for the potential. The potential employed consists of relativistic correction in the framework of pNRQCD, added to the Cornell potential. The calculated results are compared with available experimental and theoretical results.
