Abstract

We have measured the differential cross section for $\overline{p}p$ and $\mathrm{pp}$ elastic scattering at $\sqrt{s}=53$ GeV in the interval $0.5<|t|<4.0$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$ at the CERN intersecting storage rings using the split-field magnet detector. The shape of the differential cross section differs significantly between $\overline{p}p$ and $\mathrm{pp}$ scattering in the region $1.1<|t|<1.5$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$, with $\overline{p}p$ data showing a less pronounced dip structure than $\mathrm{pp}$ data.
