摘要The b (b) over bar 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-F(mu) < 0.15. A total number of 83 +/- 12b (b) over bar events is obtained with a likelihood fit of the signal and background simulated events to the data. The resulting cross section is sigma(b (b) over bar) = 17.5 +/- 2.6(stat) +/- 3.3(sys) nb/nucleon, or, when combined with a previous HERA-B measurement of similar precision, sigma(b (b) over bar) = 15.8 +/- 1.7(stat) +/- 1.3(sys)(uncorr) +/- 2.0(sys)(corr) nb/nucleon, which is consistent with recent NLO calculations.
