More than ten Ωc0 weak decay modes have been measured with the
branching fractions relative to that of Ωc0→Ω−π+. In order
to extract the absolute branching fractions, the study of
Ωc0→Ω−π+ is needed. In this work, we predict Bπ≡B(Ωc0→Ω−π+)=(5.1±0.7)×10−3
with the Ωc0→Ω− transition form factors calculated in the
light-front quark model. We also predict Bρ≡B(Ωc0→Ω−ρ+)=(14.4±0.4)×10−3 and Be≡B(Ωc0→Ω−e+νe)=(5.4±0.2)×10−3.
The previous values for Bρ/Bπ have been found to deviate
from the most recent observation. Nonetheless, our Bρ/Bπ=2.8±0.4 is able to alleviate the deviation. Moreover, we obtain
Be/Bπ=1.1±0.2, which is consistent with the current
data.Comment: 12 pages, 2 figure
