Abstract
We analyze weak decays of triply heavy baryon Ωccc++ and calculate the form factors for Ωccc++→Ξcc++/Ωcc+ transitions in a light front quark model. The momentum distributions in form factors are accessed via the pole-model parametrization. Using the results for form factors, we predict decay branching fractions for semi-leptonic decays, and obtain B(Ωccc++→Ξcc+e+νe)=0.08%, B(Ωccc++→Ωcc+e+νe)=1.23%. Forward-backward asymmetry and angular distributions are then investigated in this work. We also estimate branching fractions for a few color-allowed processes and find that the Ωccc++→Ωcc+π+ has a sizable branching fraction: B(Ωccc++→Ωcc+π+)=1.82%. We point out that the Ωccc++→Ωcc+π+ is a golden channel for the discovery of the Ωccc++. This analysis can provide a useful reference for future experimental search in future.
