Abstract

The production of beauty quarks in ep interactions has been studied with the ZEUS detector at HERA for exchanged four-momentum squared Q2>10 GeV2, using an integrated luminosity of 363 pb−1. The beauty events were identified using electrons from semileptonic b decays with a transverse momentum \(0.9 < p_{T}^{e} < 8\) GeV and pseudorapidity |ηe|<1.5. Cross sections for beauty production were measured and compared with next-to-leading-order QCD calculations. The beauty contribution to the proton structure function F2 was extracted from the double-differential cross section as a function of Bjorken-x and Q2.
