Abstract: (arXiv)

The

\Lambda_{b}(udb)

baryon is observed in the decay

\Lambda_{b}\to J/\psi \Lambda

using 6.1 fb

^{-1}

of

p\bar{p}

collisions collected with the D0 detector at

\sqrt{s}=1.96

TeV. The production fraction multiplied by the branching fraction for this decay relative to that for the decay

B^{0}\to J/\psi K^{0}_{s}

is measured to be 0.345 \pm 0.034 \mbox{ (stat.)} \pm 0.033\mbox{ (syst.)} \pm 0.003\mbox{ (PDG)}. Using the world average value of

f(b\to B^{0})\cdot\mathcal{B}(B^{0}\to J/\psi K^{0}_{s})=(1.74\pm 0.08)\times 10^{-5}

, we obtain f(b\to\Lambda_{b})\cdot \mathcal{B} \left( \Lambda_{b} \rightarrow J/\psi \Lambda \right) = (6.01\pm 0.60\mbox{ (stat.)}\pm0.58\mbox{ (syst.)} \pm 0.28 \mbox{ (PDG)})\times 10^{-5}. This measurement represents an improvement in precision by about a factor of three with respect to the current world average.
