Erratum: Bottom photoproduction measured using decays into muons in dijet events inepcollisions ats=318  GeV[Phys. Rev. D70, 012008 (2004)]

Abstract

The photoproduction of beauty quarks in events with two jets and a muon has been measured with the ZEUS detector at HERA using an integrated luminosity of 110 pb −1 . The fraction of jets containing b quarks was extracted from the transverse momentum distribution of the muon relative to the closest jet. Differential cross sections for beauty production as a function of the transverse momentum and pseudorapidity of the muon, of the associated jet and of x jets γ , the fraction of the photon's momentum participating in the hard process, are compared with MC models and QCD predictions made at next-to-leading order. The latter give a good description of the data.

Charm, beauty and top at HERA

“…Several other analyses [190,191,142] also studied x obs γ , with less statistics than but similar conclusions as for charm.…”

Heavy Flavors in High Energy ep Collisions

“…Some of the previous measurements [20,21] have found the prediction to be below the data by up to a factor 3. Recent measurements by H1 and ZEUS required events containing jets in addition to high p T muons, which are traditionally used to tag beauty quarks [22][23][24]. As shown in Fig.…”
