In this work, we study $$\Lambda _{b}\rightarrow \Lambda _{c}$$Λb→Λc and $$\Sigma _{b}\rightarrow \Sigma _{c}$$Σb→Σc weak decays in the light-front quark model. As is well known, the key point for such calculations is properly evaluating the hadronic transition matrix elements which are dominated by the non-perturbative QCD effect. In our calculation, we employ the light-front quark model and rather than the traditional diquark picture, we account the two spectator light quarks as individual… Expand

Study on $$\Xi _{cc}\rightarrow \Xi _c$$ and $$\Xi _{cc}\rightarrow \Xi '_c$$ weak decays in the light-front quark model
In this work we study the weak decays of $\Xi_{cc}\to\Xi_c$ and $\Xi_{cc}\to\Xi'_c$ in the light-front quark model. Generally, a naive, but reasonable conjecture suggests that the $cc$ subsystem inExpand

TLDR
The semileptonic decay of spin-\textonehalf{} baryons is examined in the spectator-quark model, with special attention given to decays involving baryon whose spectators are spin singlets and those whose spectator are spin triplets. Expand
