Abstract
The beauty photoproduction cross-section measurements in ep collisions at HERA are reviewed. Data samples of events having a lepton (μ or e) and two jets in the final state, have been collected with the H1 and ZEUS detectors. The beauty signals have been extracted by fitting the pTrel distribution of the data with beauty, charm and light flavor components, where pTrel is the transverse momentum of the lepton relative to the axis of the associated jet. The obtained beauty cross sections are larger than leading order Monte Carlo and next-to-leading order perturbative QCD predictions.
