Description
The branching fractions of ground state charmed baryon are not measured so far except for the $\Lambda_c$.
Only the branching fractions relative to the primary decay modes are measured.
The measurement is important to test our understanding of weak decay of baryons and measurement of absolute production cross sections.
We report first measurement of the absolute branching fraction of $\Xi_c^0$ decaying into $\Xi\pi$, $\Lambda K \pi$, and $pKK\pi$
and $\Xi_c^+$ decaying into $\Xi\pi\pi$ and $pK\pi$.
The measurement is based on Belle data set with an integrated luminosity of 711 ${\mathrm fb}^{-1}$ collected at the $\Upsilon(4S)$ resonance.
