Abstract

The production of beauty quarks in ep interactions has been studied with the ZEUS detector at HERA for exchanged four-momentum squared Q(2) > 10 GeV(2), 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 vertical bar eta(e)vertical bar < 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 F(2) was extracted from the double-differential cross section as a function of Bjorken-x and Q(2).
