Description

Beauty production has been measured in the deep inelastic scattering regime with the ZEUS detector at HERA. Beauty was reconstructed using its semi-leptonic decay into muons. The beauty signal was separated from the background using lifetime information and the transverse momentum of the muon with respect to the axis of the jet coming from the hadronisation of the b quark, ptrel. Differential cross sections were measured and compared to next-to-leading order QCD predictions. The beauty contribution to the proton structure function F2, F2bb, was extracted and compared with theoretical predictions using different parameterisations of the proton PDFs.
