High Statistics Measurement of Polarization in $\pi^- p \to K^0 \Lambda$ at 3-{GeV}/$c$ and 5-{GeV}/$c$

Snyder, A. ; Ambats, I. ; Meyer, W.T. ; et al.
Phys.Rev.D 21 (1980) 599, 1980.
Inspire Record 8072 DOI 10.17182/hepdata.24173

We have measured the polarization of the Λ hyperon produced in the reaction π−p→K0Λ at 3 and 5 GeV/c, for four-momentum transfers t′ out to 1.6 GeV2, by observing the parity-violating decay Λ→pπ−. With an increase in statistical power by a factor of 3 to 4 over the best previous experiments in this energy range, we confirm earlier observations that the polarization is small and positive below t′=0.4 GeV2, becoming large and positive for larger values of t′. In particular, at 5 GeV/c for all t′ between 0.8 and 1.6 GeV2 the polarization is consistent with a value of - 1.

A Measurement of the Anti-neutron - Proton Cross-section as Low-energy

Phys.Rev.D 23 (1981) 587, 1981.
Inspire Record 8075 DOI 10.17182/hepdata.24071

The total and annihilation cross sections of antineutrons on protons and carbon nuclei have been measured for antineutron momenta 0.25 to 0.88 GeV/c using a novel poor-geometry transmission technique. The measured cross sections are similar to antiproton cross sections in the same energy region. The presence of higher angular momenta (≥P wave) in the annihilation is confirmed down to 0.25 GeV/c. The Glauber-Wilkin correction to the p¯d total cross section is verified to 20% precision in this momentum region.

Charged-current neutrino and antineutrino interaction cross sections have been measured in the energy range 10 to 50 GeV using BEBC filled with a neon-hydrogen mixture. At these energies, σ/E was measured to be (0.73±0.08) 10−38 cm2/GeV per nucleon for neutrinos and (0.32±0.06) 10−38 cm2/GeV per nucleon for antineutrinos.

The elastic photoproduction of four pions has been studied at incident photon energies between 2.8 and 4.8 GeV. Production cross-sections are presented and an analysis of the angular decay correlations is also described, indicating a large 1− contribution in both final states, π+ π− π+ π− and π+ π− π0 π0. A quantitative understanding of these and other available 4π photoproduction data in terms of the ρ′(∼1.2GeV) and the ρ′(∼1.6) is presented.

On the Angular Dependence of Photoprotons From Nuclei Irradiated by $\gamma$ Quanta With Maximum Energy 4.5-{GeV}

Alanakian, K.V. ; Amarian, M.Dzh. ; Demirchyan, R.A. ; et al.
Nucl.Phys.A 367 (1981) 429, 1981.
Inspire Record 147184 DOI 10.17182/hepdata.18468

The angular dependences of proton photoproduction from the nuclei 12 C, 63 Cu and 208 Pb irradiated by bremsstrahlung γ-quanta with maximum energy 4.5 GeV, both in the cumulative region (i.e. in the kinematical region in which the production of protons in the collision of γ-quanta of the given energy with the quasi-free nuclear nucleon is forbidden) and in the non-cumulative region, are investigated. The experimental data obtained are compared with the results of theoretical calculations of cumulative proton photoproduction according to the following models: the “quasi-two-body” scaling model, the low-nucleon correlation model, the fluctuon model and the cluster model.
