Measurements of Polarization and Spin Rotation in Proton Proton Elastic Scattering at 3.83-GeV/c

Deregel, J. ; Bruneton, C. ; Bystricky, J. ; et al.
Nucl.Phys.B 103 (1976) 269-278, 1976.
Inspire Record 113032 DOI 10.17182/hepdata.35989

The polarization P in proton-proton elastic scattering has been measured at 3.83 GeV/ c for 0.35 ⩽ | t | ⩽ 3.0 (GeV/ c ) 2 , i.e. 29° ⩽ θ c.m. ⩽ 93°. The polarization shows a minimum at − ⋍ 1.0 ( GeV /c) 2 followed by a maximum at −⋍1.5 ( GeV /c) 2 . At the same energy the spin rotation parameter R has been measured in the interval 0.18 ⩽ | t | ⩽ 0.57 (GeV/ c ) 2 . Comparison with the results at 6.0 and 15.75 GeV/ c shows a similar t -dependence and the same average value at all three energies.

The results presented in this paper were obtained from a 105 000 frame exposure of the FNAL Hybrid Proportional Wire Chamber-30 inch Bubble Chamber System, in a tagged beam of 147 GeV/ c negative particles. Elastic, total and topological cross sections were obtained for both π − p and K − p interactions. Comparisons with other data, taken with various beam particles over large momentum intervals, show good agreement with KNO scaling, and similarity in the scaling behavior of σ n for the different beam particles.

Measurement of the Total and Partial anti-p p Cross-Section Between 1901-MeV and 1950-MeV

The CERN-Liverpool-Mons-Padua-Rome-Trieste collaboration Chaloupka, V. ; Drevermann, H. ; Marzano, F. ; et al.
Phys.Lett.B 61 (1976) 487-492, 1976.
Inspire Record 108895 DOI 10.17182/hepdata.27669

The presence of a structure in the p̄p total cross section at 1930–1940 MeV, with a narrow width of 9 MeV is confirmed. The interpretation of the effect as a single, non interfering, resonance is made difficult by the comparison of the elastic scattering with the charge exchange cross sections.

rivet Analysis
Observation of a Resonance at 4.4-GeV and Additional Structure Near 4.1-GeV in e+ e- Annihilation

Phys.Rev.Lett. 36 (1976) 700, 1976.
Inspire Record 108144 DOI 10.17182/hepdata.21093

We observe a resonancelike structure in the total cross section for hadron production by e+e− colliding beams at a mass of 4414 ± 7 MeV having a total width Γ=33±10 MeV. From the area under this resonance, we deduce the partial width to electron pairs to be Γee=440±140 eV. Further structure of comparable width is present near 4.1 GeV.

We present a comparative study of inclusive and semi-inclusive pion production in pp collisions at 102 and 400 GeV/ c . In particular, we examine the correlation between transverse and longitudinal momentum variables and the energy dependence of invariant cross sections.

Large t Elastic Proton Proton Scattering at s**(1/2) = 53-GeV

Phys.Lett.B 62 (1976) 363-365, 1976.
Inspire Record 108743 DOI 10.17182/hepdata.27660

New experimental results are presented on proton-proton elastic scattering in the range of momentum transfer 0.8GeV 2 < − t < 9 GeV 2 at a centre-of-mass energy of √ s = 53 GeV. The data are obtained sing the Split-Field- Magnet Detector at the CERN Intersecting Storage Rings. The cross section has well-known minimum at − t = (1.34±0.02) GeV 2 but no further minimum or change of slope is observed between 2 and 6.5 GeV 2 .

A Measurement of the Cross-Section of the Reaction p p --> n Delta++ (1232) at ISR Energies

Kwak, N. ; Nagy, E. ; Regler, M. ; et al.
Phys.Lett.B 62 (1976) 359-362, 1976.
Inspire Record 108757 DOI 10.17182/hepdata.27678

A measurement of the cross section of the charge-exchange reaction pp→ Δ ++ (1232)n at √ s = 23, 31 and 45 GeV at the CERN-ISR is reported. The energy dependence continues to follow a power law p lab − n with n = 1.94 ± 0.03 indicating dominance of one-pion exchange at the lowest ISR energy; there is some evidence for deviation from this at the higher ISR energies.
