| Achoimre: | <p>The development of a neural network based electron finder designed for the ZEUS calorimeter is described. A study of elastic and inelastic <em>J</em>/ψ meson production in electron-proton collisions at HERA using the ZEUS detector is presented. During the 1993 and 1994 running periods, the ZEUS detector collected ~ 500 nb<sup>-1</sup> and ~ 3 pb<sup>-1</sup> of data respectively. The direct inelastic <em>J</em>/ψ photoproduction cross-section is measured for both running periods and an attempt is made to extract the gluon density inside the proton using the 1994 inelastic <em>J</em>/ψ sample.</p> |
