The differential cross section for elastic antiproton—proton scattering at s =1.8 TeV has been measured over the t range 0.034⩽| t |⩽0.65 (GeV/ c ) 2 . A logarithmic slope parameter, B , of 16.3±0.3 (GeV/ c ) −2 is obtained. In contrast to lower energy experiments, no change in slope is observed over this t range.

Antiproton-proton elastic scattering has been measured at 3.55 GeV/ c in the c.m. angular range from 20° to 77° and from 109° to 160°. Forward elastic scattering shows a structure near t = −0.5 (GeV/ c ) 2 . In the backward region two events are observed.

Large Momentum Transfer Elastic Scattering of $\pi^{\pm}, K^{\pm}$, and $\rho^{\pm}$ on Protons at 100 GeV/c and 200 GeV/c

Inspire Record 202682 DOI 10.17182/hepdata.23648

Results are presented on π±p, K±p, and p±p elastic scattering measured with an apparatus having acceptance of 0.5<−t<2.5 (GeV/c)2 and 0.9<−t<11 (GeV/c)2 at 100 and 200 GeV/c, respectively. A diffractionlike dip is seen for the first time in the π−p t distribution at −t=4 (GeV/c)2. All meson-proton cross sections are found to be similar in the range 1<−t<2.5 (GeV/c)2, although some small systematic differences are observed. Cross sections for pp and p―p are compared with previous data.

Antiproton - Proton and Proton - Proton Elastic Scattering at 100 and 200 GeV/c

Kaplan, D.H. ; Karchin, P. ; Orear, J. ; et al.
Phys.Rev.D 26 (1982) 723, 1982.
Inspire Record 178011 DOI 10.17182/hepdata.23894

Antiproton-proton elastic scattering has been measured at 100 GeV/c for 0.5<−t<2.5 (GeV/c)2 and at 200 GeV/c for 0.9<−t<4 (GeV/c)2. The data show that the −t≃1.4 (GeV/c)2 dip recently observed at 50 GeV/c persists to higher incident momenta. Proton-proton measurements made at the same beam momenta show similar structure.
