| Abstract |
We report the first observation of beauty production in deep inelastic ep scattering (DIS). Hadrons with b flavour are observed with the H1 detector at HERA through their semi-leptonic decay. The cross section is extracted using the distributions of the impact parameter and of the transverse momentum of muons relative to jets in the kinematic range 2 < Q2 < 100 GeV2, 0.05 < y < 0.7, for muon polar angles and transverse momenta 35 < theta < 130 deg and pT > 2 GeV. The result, sigma = [39 +- 8(stat.) +- 10(syst.)]pb is found to be significantly above NLO QCD predictions. |
