Abstract
AbstractWe investigate the weak decays of the triply heavy baryon $$\Omega _{QQQ}$$
Ω
QQQ
in the light-front quark model. Since $$\Omega _{QQQ}$$
Ω
QQQ
consists of three indistinguishable identical heavy quarks, the commonly adopted quark–diquark picture does not seem to be valid anymore. Instead, we employ the three-quark picture for baryons where the three quarks are regarded as individual quarks. We calculate the hadronic form factors for the transitions and give predictions for the decay widths of the semi-leptonic decay modes $$\Omega _{ccc}\rightarrow \Xi _{cc}/ \Omega _{cc}+ l^+\nu _l$$
