Anti-p p elastic scattering at 2.33 gev/c

Crawley, H.B. ; Kernan, W.J. ; Ogino, F. ;

Inspire Record 93330 DOI 10.17182/hepdata.22080

The differential scattering cross section is presented for p¯p elastic scattering at an incident laboratory momentum of 2.33 GeV/c based upon 11 758 events. The experiment was performed at the Brookhaven National Laboratory using the 31-inch hydrogen bubble chamber and an electrostatically separated beam. The attempts to fit limited regions of the data are presented for different parametrizations. The parametrization which corresponds to two coherent interfering exponentials successfully reproduces a very large t region for the scattering.

Anti-p p elastic scattering at 2.85 gev/c

Crawley, H.B. ; Hafen, Elizabeth S. ; Kernan, W.J. ;

p¯p elastic scattering at an incident beam momentum of 2.85 GeV/c is analyzed using 18 412 events. The simple exponential parametrization of the diffraction peak is found to be a poor representation of the data. Two other parametrizations are tried and the estimates of dσdt at t=0 and of the slope of the diffraction peak are found to differ significantly between various parametrizations. It is found that two coherent interfering exponentials are able to represent the differential cross section over the range 0.04≤|t|≤1.8 (GeV/c)2 with a χ2 probability of approximately 40%.

Phys.Lett.B 128 (1983) 336, 1983.
Inspire Record 190339 DOI 10.17182/hepdata.30668

Proton-antiproton elastic scattering at CM energy 540 GeV has been studied in the t -range 0.04 < − t < 0.45 GeV 2 . The data are well fitted by the form exp ( bt ) with b = 17.1 ± 1.0 GeV −2 for | t | = 0.04 − 0.18 GeV su 2 and b = 13.7 ± 0.2 ± 0.2 GeV −2 for | t | = 0.21−0.45 GeV 2 . A luminosity measurement combined with the optical theorem gives σ tot = 67.6 ± 5.9 ± 2.7 mb and σ e1 / σ tot = 0.209 ± 0.018 ± 0.008.

Measurement of small angle anti-proton - proton elastic scattering at S**(1/2) = 546-GeV and 1800-GeV

The CDF collaboration Abe, F. ; Albrow, Michael G. ; Amidei, Dante E. ; et al.
Phys.Rev.D 50 (1994) 5518-5534, 1994.
Inspire Record 359411 DOI 10.17182/hepdata.22369

Antiproton-proton elastic scattering was measured at c.m.s. energies √s =546 and 1800 GeV in the range of four-momentum transfer squared 0.025<-t<0.29 GeV2. The data are well described by the exponential form ebt with a slope b=15.28±0.58 (16.98±0.25) GeV−2 at √s =546 (1800) GeV. The elastic scattering cross sections are, respectively, σel=12.87±0.30 and 19.70±0.85 mb.
