Description

The reduced cross sections for $e^{+}p$ deep inelastic scattering have been measured with the ZEUS detector at HERA at three different centre-of-mass energies, $318$, $251$ and $225$ GeV. The cross sections, measured double differentially in Bjorken $x$ and the virtuality, $Q^2$, were obtained in the region $0.13\ \leq\ y\ \leq\ 0.75$ and $5\ \leq\ Q^2\ \leq\ 110$ GeV$^2$, where $y$ denotes the inelasticity. The proton structure functions $F_2$ and $F_L$ were extracted from the measured cross sections.
