The b over(b, ̄) production cross section in 920 GeV proton-nucleus fixed target collisions is measured by observing double muonic decays of b-flavoured hadrons in the kinematic region - 0.3 < x (μ) < 0.15. A total number of 83 ± 12 b over(b, ̄) events is obtained with a likelihood fit of the signal and background simulated events to the data. The resulting cross section is σ = 17.5 ± 2.6 ± 3.3 nb / nucleon, or, when combined with a previous HERA-B measurement of similar precision, σ = 15.8 ± 1.7 ± 1.3 ± 2.0 nb / nucleon, which is consistent with recent NLO calculations. © 2007.
