Beauty Quark Production in Deep Inelastic Scattering at HERA
Abstract
Description
The measurement of the beauty quark production cross section in deep inelastic scattering with the ZEUS detector at HERA is presented. The cross section for beauty quarks, measured in the kinematic range $Q^2 > 2$ GeV$^2$ and $0.05 < y < 0.7$, and for events with at least one muon and one jet in the Breit frame, is somewhat above the next-to-leading order (NLO) QCD prediction, but in agreement within the experimental and theoretical uncertainties.
