摘要

In this work we study the weak decays of Xi cc ->Xi c and Xi cc ->Xi c ' in the light-front quark model. Generally, a naive, but reasonable conjecture suggests that the cc subsystem in Xi cc ( us pair in Xi c(') stands as a diquark with definite spin and color assignments. During the concerned processes, the diquark of the initial state is not a spectator, namely must be broken. A Racah transformation would decompose the original (cc)q into a combination of c(cq) components. Thus we may deal with the decaying c quark alone while keeping the (cq) subsystem as a spectator. With the re-arrangement of the inner structure we calculate the form factors numerically and then obtain the rates of semi-leptonic decays and non-leptonic decays, which will be measured in the future.
