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.

Total cross-sections for pi- p ---> lambda k0 from threshold to 1.13 gev/c

Jones, J.J. ; Bowen, T. ; Dawes, W.R. ; et al.
Phys.Rev.Lett. 26 (1971) 860-863, 1971.
Inspire Record 69027 DOI 10.17182/hepdata.21505

Total cross sections for π−p→ΛK0 have been measured using optical spark chambers from threshold to 1.13−GeVc beam momentum in 19−MeVc intervals, but with a 1−MeVc resolution in the regions of the ΛK and ΣK thresholds. The behavior near ΛK threshold indicates a significant s-wave contribution, but this experiment is unable to resolve any cusplike behavior in the region of the ΣK thresholds. The cross section shows a broad peak in the vicinity of 1.05−GeVc beam momentum.

Isobar production and elastic scattering in p p interactions from 6-GeV/c to 30-GeV/c

Edelstein, R.M. ; Carrigan, Richard A., Jr. ; Hien, N.C. ; et al.
Phys.Rev.D 5 (1972) 1073-1096, 1972.
Inspire Record 67297 DOI 10.17182/hepdata.22467

Differential cross sections have been measured for nucleon-isobar production and elastic scattering in p−p interactions from 6.2 to 29.7 GeVc in the laboratory angle range 8<θsc<265 mrad. N*' s at 1236, 1410, 1500, 1690, and 2190 MeV were observed. Computer fits to the mass spectra under varying assumptions of resonance and background shapes show that conclusions on t and s dependence are only slightly affected despite typical variations in absolute normalization of ± 35%. Logarithmic t slopes in the small- |t| range are ∼15 (GeVc)−2 for the N*(1410), ∼5 (GeVc)−2 for the N*'s at 1500, 1690, and 2190 MeV, and ∼9 (GeVc)−2 for elastic scattering. Also for the small- |t| data, cross sections for N*'s at 1410, 1500, 1690, and 2190 MeV and for elastic scattering vary only slightly with Pinc consistent with the dominance of Pomeranchuk exchange and with diffraction dissociation. A fit of N*(1690) total cross sections to the form σ∝P−n gives n=0.34±0.06, while for elastic scattering n=0.20±0.05. For the N*(1690) the effective Regge trajectory has the slope αeff′(0)=0.38±0.17. When compared with N* production in π−, K−, and p¯ beams these data also agree with approximate factorization of the Pomeranchuk trajectory. N*(1236) cross sections are consistent with other measurements at similar momenta. For −t>1 (GeVc)−2, elastic scattering cross sections decrease approximately as Pinc−2, and they and N*(1500)− and N*(1690)− production cross sections have t slopes consistent with 1.6 (GeVc)−2.

Neutral associated production by 8, 10.7 and 15.7 gev/c pi- incident on protons

Foley, K.J. ; Love, W.A. ; Ozaki, S. ; et al.
Phys.Rev.D 8 (1973) 27-38, 1973.
Inspire Record 81979 DOI 10.17182/hepdata.22059

We present differential and total cross sections for two reactions: π−p→K0Λ and π−p→K0Σ0. The incident pion momenta were 8, 10.7, and 15.7 GeVc. The results are based on an analysis of approximately 22 600 events of the two reactions where the π+ and π− from the decay of the KS0 were detected in the forward leg of the Double Vee Magnetic Spectrometer. The separation of Λ recoils from Σ0 recoils was accomplished by the missing-mass technique.

Analysis of the q in k- d ---> k- pi- pi+ d and k- d ---> k- pi- pi+ n p(s) at 7.3 gev/c

Anderson, K.J. ; Franklin, A.D. ; Godden, G.D. ; et al.
Phys.Rev.D 6 (1972) 1823-1833, 1972.
Inspire Record 83144 DOI 10.17182/hepdata.22254

Results from the study of reactions (1) K−d→K−π−π+d and (2) K−d→K−π−π+nps at 7.3 GeV/c are presented. The interactions are dominated by the production of K*(890), ρ(765), Q(1200−1450), and D*(2200) in (1) and Δ−(1236) in (2). Observation of ρ(765) and its possible source as a misidentified K*(890) is discussed. Evidence is observed of splitting of the Q into two resonances with masses and widths (in MeV) M1=1228±21, Γ1=111±33, M2=1414±15, and Γ2=89±24, L(1775) is observed in (1). An off-shell one-pion-exchange-model calculation is compared to (2). Cross sections and branching ratios of the Q resonances are estimated on the basis of the model.

Measurements of the differential cross-section of the reaction p p ---> d pi+ from 3.0 to 5.0 gev/c

Anderson, H.L. ; Larson, D.A. ; Myrianthopoulos, L.C. ; et al.
Phys.Rev.D 9 (1974) 580-596, 1974.
Inspire Record 93111 DOI 10.17182/hepdata.21941

A measurement of the complete differential cross section for the reaction pp→dπ+ at 3.00, 3.20, 3.43, 3.65, 3.83, 4.00, 4.20, and 5.05 GeVc incident proton momentum has been made in an attempt to establish the role of the Δ (1950) in this region. The data show that the previously observed enhancement in the forward cross section between 3 and 4 GeVc due to this isobar is an effect which damps out quickly as the production angle departs from zero degrees, in contrast with the well-known enhancement at 1.35 GeVc, which is evident at all angles. In particular, the one-pion-exchange model is in poor agreement with the extended set of data. A detailed description is given of a novel proportional-wire-chamber system which facilitated the selection of this rather rare reaction from a very high competing background.
