Abstract

The production of heavy quarks has been studied in photoproduction processes with the ZEUS detector at HERA using an integrated luminosity of $36.9 p b^{- 1}$ . Events with a photon virtuality, $Q^{2} < 1 G e V^{2}$ , were selected with two jets of high transverse energy and an electron in the final state. Consideration of the distribution in $p_{T}^{r e l}$ - the momentum of the electron transverse to the axis of the jet to which the electron is closest - allows a measurement of the beauty cross-section in a restricted region of phase space.
