abstract
In this work we calculate the branching ratios of semi-leptonic and non-leptonic decays of $\Lambda_b$ into light baryons ($p$ and $\Lambda$), as well as the measurable asymmetries which appear in the processes, in the light front quark model (LFQM). In the calculation, we adopt the diquark picture and discuss the justifiability of applying the picture in our case. Our result on the branching ratio of $\Lambda_b\to\Lambda+J/\psi$ is in good agreement with data. More predictions are made in the same model and the results will be tested in the future experiments which will be conducted at LHCb and even ILC.

Study of $\Lambda^0_b \to \Lambda D$ decays with the rescattering mechanism
Rescattering enhances the anti-D0 Lambda branching fraction by two orders of magnitude and produces large direct CP asymmetries (0.28 and -0.14) in Lambda_b to Lambda D channels.
