000168462 520__ $$aBeauty quark production via the process ep → e′b b → e′ µ µ X has been measured in ep collisions with the ZEUS detector at HERA. The ZEUS muon-detection system gives access to the full phase space. Dimuon charge correlations as well as hadronic isolation and the mass of the dimuon system were used to separate the beauty signal from backgrounds. For this analysis information from secondary vertices is used for further separation. Measured visible, differential and total cross sections for beauty quark production are compared to next-to-leading order QCD calculations and previous measurements. A search for QCD instanton-induced processes containing both a charm- and beauty-quark pair is also performed. In order to differentiate between beauty and instanton events, discriminating observables sensitive to the hadronic final state, so-called event shape variables, were used in combination with the dimuon and vertex requirements.
