Observation of a New Structure in the Difference Between the $p p$ Total Cross-sections for Antiparallel and Parallel Longitudinal Spin States

Auer, I.P. ; Colton, E. ; Halpern, H. ; et al.
Phys.Rev.D 34 (1986) 2581, 1986.
Inspire Record 230143 DOI 10.17182/hepdata.23425

We have measured the difference between the pp total cross sections for parallel and antiparallel longitudinal spin states at beam momenta of 2.75, 2.92, 3.25, and 3.48 GeV/c. These results reveal possible new structure in this momentum range.

Observation of Structures in the p p Total Cross-Section Difference of Pure Helicity States in the Mass Range of 2100-MeV to 2500-MeV

Auer, I.P. ; Colton, E. ; Halpern, H. ; et al.
Phys.Rev.Lett. 41 (1978) 354-356, 1978.
Inspire Record 135492 DOI 10.17182/hepdata.20831

We have measured the difference between the pp total cross sections for parallel and antiparallel longitudinal spin states at beam momenta of 1.0, 1.1, 1.30, 1.58, 1.71, 2.1, and 2.25 GeV/c in a transmission counter experiment. These results reveal new structure in the plab range of 1.0 to 2.5 GeV/c.

Measurement of the Total Cross-Section Difference for p p Scattering in Longitudinal Spin States

Auer, I.P. ; Colton, E. ; Hill, D. ; et al.
Phys.Lett.B 67 (1977) 113-116, 1977.
Inspire Record 4411 DOI 10.17182/hepdata.27581

We have measured the total cross-section difference for pp scattering in initial spin states parallel to the beam direction at beam momenta of 1.17, 1.47, 1.69, 1.97 and 2.49 GeV/ c . This measurement was done in a standard transmission experiment. A striking energy dependence is observed with a maximum difference of −16.9 mb at P lab = 1.47 GeV/ c .

Proton-Proton Interactions at 2.75 Bev

Block, M.M. ; Harth, E.M. ; Cocconi, V.T. ; et al.
Phys.Rev. 103 (1956) 1484-1489, 1956.
Inspire Record 945002 DOI 10.17182/hepdata.26908

212 interactions of 2.75-Bev protons have been observed in a hydrogen-filled diffusion cloud chamber. The data indicate an elastic cross section of 15 millibarns, with about 9 millibarns cross section for single pion production, 13 millibarns for double, and 4 for triple. There is one example of quadruple pion production. One definite example of the production of heavy unstable particles was observed, and two doubtful cases. The median elastic scattering angle was 19° in the c.m. system. Angle and momentum distributions for inelastic events are consistent with those observed at lower energies.
