The Heavy Quark Effective Theory provides a systematic method to estimate a mixing angles of hadron states in a heavy quark, such as charm quark (c) and bottom quark (b). Using this method, we can estimate the mixing angles of the baryons ΞQΞQ. The mixing angles between ΞQ and ΞQ are given by |θb|=4.51±0.79 for the Q=b case and |θc|=8.12±0.80 for the Q=c case.

混合角度 Ξ-Ξ 在重夸克有效理论中

重夸克有效理论提供了一种系统的方法来估算重夸克(例如魅力夸克(c)和底夸克(b))中强子态的混合角。使用这种方法,我们可以估计重子的混合角度Ξ-Ξ。之间的混合角度ΞΞ|θb|=4.51±0.79 为了 =b 情况和 |θC|=8.12±0.80 为了 =C 案件。
