论文摘要
研究了在非相关夸克模型的框架中，研究了地面双重重气子的静态特性和半衰减的衰变。使用现象学的潜在模型，我们计算了双重重$ω$和$ξ$ baryons的地面质量和磁矩。在重型夸克限制中，我们引入了一种简单的ISGUR智能函数的简单形式，然后研究了$ \ frac {1} {1} {1} {2} \ rightArrow \ rightArrow \ rightarrow \ frac \ frac {1}的独家$ b \ rightarrow c $ emerptonic衰减宽度和分支比率。我们获得的结果与其他理论预测一致。
The static properties and semileptonic decays of ground-state doubly heavy baryons are studied working in the framework of a non-relativistic quark model. Using a phenomenological potential model, we calculate the ground-state masses and magnetic moments of doubly heavy $ Ω$ and $ Ξ$ baryons. In the heavy quark limit, we introduce a simple form of the universal Isgur-Wise function used as the transition form factor and then investigate the exclusive $ b \rightarrow c $ semileptonic decay widths and branching ratios for $ \frac{1}{2}\rightarrow \frac{1}{2} $ baryon transitions. Our obtained results are in agreement with other theoretical predictions.
