摘要

在超中心构成夸克模型的框架内研究了重子（\Lambda _b\）半轻子衰变的伊斯古尔-维斯函数（Isgur-Wise function）。通过变分法求解六维超径向薛定谔方程，得到重重子的质量和波函数。得到的 Isgur-Wise 函数与其他理论工作进行了比较。确定了伊斯古尔-怀斯函数的斜率（\(\rho ^2\)），发现计算得到的伊斯古尔-怀斯函数的斜率（\(\rho ^2\)）与其他理论预测和现有实验观测结果一致。

Isgur–Wise function for the semileptonic decay of \(\Lambda _b\) baryon

The Isgur–Wise function for the semileptonic decay of \(\Lambda _b\) baryon is studied in the framework of the Hypercentral Constituent Quark Model. The six-dimensional hyperradial Schrödinger equation is solved in the variational approach to get masses and wavefunctions of heavy baryons. The obtained Isgur–Wise function is compared with the other theoretical work. The slope (\(\rho ^2\)) of the Isgur–Wise function is determined and it is found that the computed slope (\(\rho ^2\)) of the Isgur–Wise function is in accordance with other theoretical predictions and with the available experimental observations.
