Dip Movement inpp¯andppElastic Collisions

It is pointed out that the recently discovered dip in elastic $p\overline{p}$ cross section is related to the dips at lower $\mathrm{}\left|t\right|\mathrm{}$ and lower energies, consistent with the geometrical picture of high-energy scattering. At 30 GeV/c incoming energy, the dip is predicted by interpolation to occur at $-t=1.1\mathrm{}$ (GeV/${\mathit{c})}^2$. The curve for dip position versus ${\sigma }_T$ is discussed.
