Abstract

Evidence of bottom-quark-state production has been searched for in $p$ -Fe interactions at 400 GeV/c by looking for multimuon final states. Muons in such final states could come from $B \to ψ \to 2 μ$ decay accompanied by a muonic decay of $\bar{B}$ (or $\bar{B} \to \bar{D} \to μ$ chain) or from a combination of $B$ and $D$ muonic decays. With the assumption of a 10% branching ratio for $B \to μ X$ , a search for several specific decay modes yields an upper limit for the $B$ production cross section of ≲ 50 nb/nucleon.
