Anti-proton-proton elastic scattering at 3.55 gev/c

Baker, W.F. ; Carlson, P.J. ; Chabaud, V. ; et al.
Nucl.Phys.B 12 (1969) 5-8, 1969.
Inspire Record 56106 DOI 10.17182/hepdata.35577

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.

Anti-p-p elastic scattering at 8 and 16 gev/c

Birnbaum, D. ; Edelstein, R.M. ; Hien, N.C. ; et al.
Phys.Rev.Lett. 23 (1969) 663-666, 1969.
Inspire Record 56380 DOI 10.17182/hepdata.3393

Angular distributions are presented for p¯−p elastic scattering at 8 and 16 GeV/c for |t|<1.3 (GeV/c)2. At both energies there is structure in the differential cross sections in the region 0.5<~|t|<~1.0 (GeV/c)2, similar to that observed at lower energies. The diffraction peak continues to expand with increasing incident momentum.

Anti-p-p backward elastic scattering from 0.7 to 2.16 gev/c

Yoh, J.K. ; Barish, B.C. ; Nicholson, H. ; et al.
Phys.Rev.Lett. 23 (1969) 506-510, 1969.
Inspire Record 56393 DOI 10.17182/hepdata.3399

Elastic scattering of p¯ on p has been studied for cosθc.m. between -0.88 and -1.0 and Plab(p¯) between 0.70 and 2.16 GeV/c. The momentum dependence of the cross section shows a sharp dip at 0.9 GeV/c and a broad peaking around 1.4 GeV/c. The possibility of the peak resulting from direct formation of boson resonances has been studied. Alternatively, a diffraction model agrees qualitatively with our data and other elastic data at different angles.

Upper limits on rare two-body processes in k- p and anti-p p scattering at high energies

Inspire Record 63230 DOI 10.17182/hepdata.6079

A missing mass spectrometer search was made for several two-body, double charge exchange reactions, including backward K −p and p̄p elastic scattering at 8 and 16 GeV/ c and small momentum transfer. No examples of any of these processes were observed.

Anti-p p elastic scattering at 2.33 gev/c

Crawley, H.B. ; Kernan, W.J. ; Ogino, F. ;
Phys.Rev.D 8 (1973) 2781-2784, 1973.
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.

Antiproton-proton elastic scattering data at 6.2 GeV/ c in the range 0.3 (GeV/ c ) 2 ⩽ − t ⩽ 10.0 (GeV/ c ) 2 is presented. The experiment, using spark chambers and proportional chambers, was performed at the CERN Proton Synchroton.

Polarization Measurements in pi- p, K- p and p p Elastic Scattering at 40-GeV/c

The Saclay-Serpukhov-Dubna-Morsoc collaboration Gaidot, A. ; Bruneton, C. ; Bystricky, J. ; et al.
Phys.Lett.B 57 (1975) 389-392, 1975.
Inspire Record 99592 DOI 10.17182/hepdata.27840

We report final results on the polarization parameter P in elastic scattering of π − , K − and antiprotons at 40 GeV/ c incident momentum. The energy dependence of P (t) in π − p above 10 GeV/ c is well fitted by P (t) α s αR(t)-α P (t) where α R (t) are the effective Regge and Pomeron trajectories respectively. The data in K − p are compatible with exchange degeneracy. The results inp¯p show an important structure for |t|> 0.3 (GeV/c) 2 demonstrating the existence of a large helicity flip amplitude.

Diffractive Dissociation of the Beam Particle in anti-p p Interactions at 32.1-GeV/c

The French-Soviet union & CERN-Soviet union collaborations Grard, F. ; Kesteman, J. ; Laurent, J. ; et al.
Phys.Lett.B 59 (1975) 409, 1975.
Inspire Record 98777 DOI 10.17182/hepdata.27764

We report the results of a study of the reaction p p → p + x at 32.1 GeV c , where the recoiling proton has a small laboratory momentum. The reaction is studied in the 4.5 m Mirabelle bubble chamber at Serpukhov. We compare the diffractive dissociation of the incident antiproton to other incident particles.
