Revisiting ${\Lambda }_b\to {\Lambda }_c$ and ${\Sigma }_b\to {\Sigma }_c$ weak decays in the light-front quark model

Hong-Wei Ke, Ning Hao, Xue-Qian Li

In this work, we study ${\Lambda }_b\to {\Lambda }_c$ and ${\Sigma }_b\to {\Sigma }_c$ weak decays in the light-front quark model. As is well known, the key point for such calculations is properly evaluating…
