论文摘要
重夸克有效理论提供了一种系统的方法，可以在重夸克中估计强子状态的混合角，例如魅力夸克（c）和底部夸克（b）。通过使用此方法，可以估计Baryons $ \ varxi_q- \ varxi_q- \ varxi_q'$的混合角度。发现$ \ varxi_q $和$ \ varxi_q'$之间的混合角由$θ_b= 4.51 ^{\ circ} \ pm 0.79 ^{\ circ} $ for $ q = b $ = b $ case和$θ_ccase和$θ_c= 8.12 ^{\ circ} {\ circ} {\ pm pm 0.80 ^$ cicc = $ circ}
The Heavy Quark Effective Theory provides a systematic method to estimate a mixing angle of hadron states in a heavy quark, such as the charm quark (c) and the bottom quark (b). By using this method, the mixing angle of the baryons $\varXi_Q-\varXi_Q'$ can be estimated. It is found that the mixing angle between $\varXi_Q$ and $\varXi_Q'$ is given by $θ_b = 4.51^{\circ} \pm 0.79 ^{\circ}$ for $Q = b$ case and $θ_c = 8.12^{\circ} \pm 0.80 ^{\circ}$ for $Q = c$ case.
