Measurement of the proton structure functionF 2 from the 1993 HERA data

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The ZEUS detector has been used to measure the proton structure functionF 2. 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<104 GeV2 andx values as low as 3×10−4. The rapid rise inF 2 asx decreases observed previously is now studied in greater detail and persists forQ 2 values up to 500 GeV2.
