Query: Searches for $B^{0}_{(s)} \rightarrow J/{\psi} p \overline{p}$ and
  $B^{+} \to J/{\psi} p \overline{p} {\pi}^{+}$ decays   The results of searches for $B^{0}_{(s)} \rightarrow J/{\psi} p \overline{p}$
and $B^{+} \to J/{\psi} p \overline{p} {\pi}^{+}$ decays are reported. The
analysis is based on a data sample, corresponding to an integrated luminosity
of 1.0 fb$^{-1}$ of $pp$ collisions, collected with the LHCb detector. An
excess with 2.8$\,\sigma$ significance is seen for the decay $B^{0}_{s} \to
J/{\psi} p \overline{p}$ and an upper limit on the branching fraction is set at
the 90 % confidence level: ${\cal B}(B^{0}_{s} \to J/{\psi} p \overline{p}) <
4.8 \times 10^{-6}$, which is the first such limit. No significant signals are
seen for $B^{0} \to J/{\psi} p \overline{p}$ and $B^{+} \to J/{\psi} p
\overline{p} {\pi}^{+}$ decays, for which the corresponding limits are set:
${\cal{B}}(B^{0} \to J/{\psi} p \overline{p}) < 5.2 \times 10^{-7}$, which
significantly improves the existing limit; and ${\cal{B}}(B^{+} \to J/{\psi} p
\overline{p} {\pi}^{+}) < 5.0 \times 10^{-7}$, which is the first limit on this
branching fraction.
