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→ψ→2μ decay accompanied by a muonic decay of B̅ (or B̅ →D̅ →μ chain) or from a combination of B and D muonic decays. With the assumption of a 10% branching ratio for B→μX, a search for several specific decay modes yields an upper limit for the B production cross section of ≲ 50 nb/nucleon.
