Measurement of the proton structure function F_2 using the hadron electron separator of the ZEUS detector at HERA

By K. Ohrenberg and Hamburg (Germany) Deutsches Elektronen-Synchrotron (DESY)

Abstract

The proton structure function F_2 has been extracted from data taken by the ZEUS experiment in the year 1994. The usable integrated luminosity for this analysis was 1.54 pb"-"1 and the analysis covered the kinematic range of 4.10"-"4 < x < 7.10"-"2 and 2.5 < Q"2 < 450 GeV"2. The hadron electron separator (HES) of the ZEUS experiment has been used to improve the identification of the scattered electrons at low energies. By combining the ZEUS neural network electron finder SINISTRA and the HES it was possible to extend the measurement of the structure function F_2 down to electron scattering energies of 6 GeV. The results of this analysis are compared to the 1994 measurements of ZEUS and Hl.
