Query: A comprehensive analysis of weak transition form factors for doubly
  heavy baryons in the light front approach   The transition form factors for doubly heavy baryons into a spin-$1/2$ or
spin-$3/2$ ground-state baryon induced by both the charged current and the
flavor changing neutral current are systematically studied within the
light-front quark model. In the transition the two spectator quarks have two
spin configurations and both are considered in this calculation. We use an
updated vertex functions, and inspired by the flavor SU(3) symmetry, we also
provide a new approach to derive the flavor-spin factors. With the obtained
transition form factors, we perform a phenomenological study of the
corresponding semi-leptonic decays of doubly heavy baryons induced by the $c\to
d/s \ell^+\nu$, $b\to c/u\ell^-\bar \nu$ and $b\to d/s\ell^+\ell^-$. Results
for partial decay widths, branching ratios and the polarization ratios
$\Gamma_{L}/\Gamma_{T}$s are given. We find that most branching ratios for the
semi-leptonic decays induced by the $c\to d,s$ transitions are at the order of
$10^{-3}\sim10^{-2}$, which might be useful for the search of other
doubly-heavy baryons. Uncertainties in form factors, the flavor SU(3) symmetry
and sources of symmetry breaking effects are discussed. We find that the SU(3)
symmetry breaking effects could be sizable in charmed baryon decays while in
the bottomed case, the SU(3) symmetry breaking effects are less significant.
Our results can be examined at the experimental facilities in the future.
