Inclusive $\Upsilon$ Production in Hadronic Z Decays
A search is performed for the \ups, \upss\ and \upsss\ states, decaying into either $e^+e^-$ or \mumu, in a sample of 3.8 million hadronic $\rm{Z}$ decays collected by the ALEPH detector from 1992 to 1995. After kinematic and topological cuts a total of $1.2 \pm 0.4$ background events are expected f...

| description | A search is performed for the \ups, \upss\ and \upsss\ states, decaying into either $e^+e^-$ or \mumu, in a sample of 3.8 million hadronic $\rm{Z}$ decays collected by the ALEPH detector from 1992 to 1995. After kinematic and topological cuts a total of $1.2 \pm 0.4$ background events are expected for both channels in the mass window chosen. Two events are observed, allowing the following 95\+onfidence level branching fraction upper limit to be derived: \[\br <7.3 \times 10^{-5}.\] |
