Abstract

The beauty production cross section for deep inelastic scattering events with at least one hard jet in the Breit frame together with a union has been measured, for photon virtualities Q(2) gt 2 GeV2, with the ZEUS detector at HERA using integrated luminosity of 72 pb(-1) The total visible cross section is sigma(bb)- (ep → e jet muX) = 40.9 +/- 5.7 (stat.) (+6.0)(-4.4) (syst) pb. The next-to- leading order QCD prediction lies about 2.5 standard deviations below the data. The differential cross sections are in general consistent with the NLO QCD predictions; however at low values of Q(2), Bjorken x, and muon transverse momentum, and high values of jet transverse energy and muon pseudorapidity, the prediction is about two standard deviations below the data.
