The ZEUS detector has been used to measure the proton structure function F2. During 1993 HERA collided 26.7 GeV electrons on 820 GeV protons. The data sample corresponds to an integrated luminosity of 0.54 pb^(–1), representing a twenty fold increase in statistics compared to that of 1992. Results are presented for 7 < Q^2 < 10^4 GeV^2 and x values as low as 3×10^(–4). The rapid rise in F2 as x decreases observed previously is now studied in greater detail and persists for Q^2 values up to 500 GeV^2.

Abstract
The ZEUS detector has been used to measure the proton structure function F2. During 1993 HERA collided 26.7 GeV electrons on 820 GeV protons. The data sample corresponds to an integrated luminosity of 0.54 pb^(–1), representing a twenty fold increase in statistics compared to that of 1992. Results are presented for 7 < Q^2 < 10^4 GeV^2 and x values as low as 3×10^(–4). The rapid rise in F2 as x decreases observed previously is now studied in greater detail and persists for Q^2 values up to 500 GeV^2.File in questo prodotto:
