Observation of the decay B0bar -> LambdaC antiproton pi0
Ebert, Marcus.
In a sample of 467 million $B\overline B$ pairs collected with the
BABAR detector at the PEP-II collider at SLAC we have observed the decay
$\overline{B}^0\rightarrow\Lambda_c^ {\overline p} \pi^0$ and measured the branching fraction to be
$(1.94\pm0.17 \pm 0.14 \pm 0.50)\times 10^{-4}$,
where the uncertainties are statistical, systematic, and the uncertainty on the $\Lambda_c^ \rightarrow p {K^-} \pi^ $ branching fraction, respectively.
We determine an upper limit of $1.5\times 10^{-6}$ at $90... Show Full Abstract
In a sample of 467 million $B\overline B$ pairs collected with the
BABAR detector at the PEP-II collider at SLAC we have observed the decay
$\overline{B}^0\rightarrow\Lambda_c^ {\overline p} \pi^0$ and measured the branching fraction to be
$(1.94\pm0.17 \pm 0.14 \pm 0.50)\times 10^{-4}$,
where the uncertainties are statistical, systematic, and the uncertainty on the $\Lambda_c^ \rightarrow p {K^-} \pi^ $ branching fraction, respectively.
We determine an upper limit of $1.5\times 10^{-6}$ at $90\%$ C.L. for the product branching fraction ${\cal B} (\overline{B}^0\rightarrow
\Sigma_c^ (2455)\overline p)\times{\cal B} (\Lambda_c^ \rightarrow p K^- \pi^ )$.
Furthermore, we observe an enhancement at the threshold of the invariant mass of the baryon-antibaryon pair.
