论文摘要
受到$ b $和$ b_s $ meson状态的启发,我们在lhcb \ cite {aaij:2020hcw}的启发下,我们计算了地面的质量,轨道和径向兴奋的状态。此外,我们估计混合参数,衰减常数,松弛衰减宽度和相应的分支比以及电磁过渡宽度。 $ {\ cal {o}} \ left(\ frac {1} {m} \ right)$和$ {\ cal {o}}}(p^{10})$对潜在的相对论校正对潜在的和动能项的相对校正已添加到汉密尔顿。通过应用高斯波函数来解决所采用的筛选电位。估计的群众用于构建Regge轨迹,这有助于我们在一些新观察到的州与$ b $和$ b_s $ Meson家族的关联。总体而言,本研究的结果与可用的实验和理论研究一致。
Inspired by the recent observations of $B$ and $B_s$ meson states at LHCb\cite{Aaij:2020hcw} we calculate the masses of ground, orbitally, and radially excited states. Also, we estimate the mixing parameters, decay constant, leptonic decay width, and corresponding branching ratios, as well as electromagnetic transition widths. ${\cal{O}}\left(\frac{1}{m}\right)$ and ${\cal{O}}(p^{10})$ relativistic corrections to potential and kinetic energy terms have been added to the Hamiltonian. The screening potential employed is solved by applying the gaussian wave function. The estimated masses are used to construct the Regge trajectories, which help us in the association of some newly observed states to $B$ and $B_s$ meson family. Overall, the results from the present study are in fair agreement with available experimental and theoretical studies.
