Measurement of open beauty production at HERA

Measurement of open beauty production at HERA

The first observation of open b production in ep collisions is reported. An event sample containing muons and jets has been selected which is enriched in semileptonic b quark decays. The visible cross section σ(ep → b b ̄ X → μ X′) for Q 2
