Production and Decay of xi* (1820) in K- p Reactions at 4.2-GeV/c

The Amsterdam-CERN-Nijmegen-Oxford collaboration Gay, J.B. ; Armenteros, R. ; Berge, J.P. ; et al.

Phys.Lett.B 62 (1976) 477-480, 1976.

Inspire Record 108822 DOI 10.17182/hepdata.27651

Using a high statistics sample of K − p interactions at 4.2 GeV/ c , the production and decay properties of the Ξ ∗ (1820) are discussed. The mass and width are found to be M = (1823 ± 2) MeV and Γ = (21 ± 7) MeV. Evidence is found for Ξ ∗ (2030) in the Σ K ̄ channel and for a new Ξ ∗ at a mass of 2120 MeV in the ΛK − channel.

New Measurement of the Production Polarization and Magnetic Moment of the Cascade Minus Hyperon

Trost, L.H. ; McCliment, E.R. ; Newsom, C.R. ; et al.

Phys.Rev.D 40 (1989) 1703, 1989.

Inspire Record 280604 DOI 10.17182/hepdata.23053

We have measured the production polarization and magnetic moment of a sample of 89×103Ξ− hyperons produced in the inclusive reaction p(400 GeV/c)+Cu→Ξ−+X. The weighted average of the polarization is -0.070±0.008±0.010 at a pt of 0.63 GeV/c. The Ξ−'s magnetic moment yields the value μΞ=−0.661±0.036±0.036 nuclear magnetons. The first error is statistical, the second systematic.

Backward Production of a Spin Parity 1+ rho pi Enhancement at 1.04-GeV

The Amsterdam-CERN-Nijmegen-Oxford collaboration Gavillet, P. ; Berge, J.P. ; Ferrando, A. ; et al.

Phys.Lett.B 69 (1977) 119, 1977.

Inspire Record 120469 DOI 10.17182/hepdata.27551

A spin-parity 1 + ϱπ enhancement is observed for the 3π mass spectrum in the reaction K − p → Σ − π + π + π − where events with a small (K − → Σ − ) momentum transfer are selected. The mass (1040 MeV) and width (230 MeV) of this enhancement are reminiscent of the A 1 → ϱπ bump which has mainly been observed in the diffractive-like processes. The cross section for this enhancement at 4.15 GeV/ c incident K − momentum is (3.6 ± 0.5) μ b.

Significant production of (2030) is observed in the channel K − p → (Σ K − K + from a high statistics bubble chamber exposure at 4.2 GeV/ c . The mass and width are determined to be 2024 ± 2 MeV and 16 ± 5 MeV respectively. Apart from Σ K , the only other decay channel is found to be Λ K .

250-{GeV}/$c \pi^- p$ Multiplicity Distributions and the Two Component Model

Hays, P.J. ; Diamond, R.N. ; Clark, R.K. ; et al.

Phys.Rev.D 23 (1981) 20, 1981.

Inspire Record 144125 DOI 10.17182/hepdata.24140

The charged-particle multiplicity distribution from 250-GeV/c π−p interactions in the Fermilab 15-ft bubble chamber is presented. The corrections to the raw data are described. Fits to these data along with other high-energy bubble-chamber data show that cluster models with two components—a low-multiplicity, diffractive component and a high-multiplicity, nondiffractive component—describe the data fairly well. The charged multiplicity of each cluster is found to be ∼2, while the number of clusters for each component grows linearly with ln(s). The multiplicity moments are consistent with other experiments. We find 〈nc〉=8.427±0.059, f2cc=8.66±0.11, 〈nc〉D=2.038±0.023. The total inelastic cross section is σI=21.42±0.50 mb.

Inclusive Negative Hadron Production from High Energy $\bar{\nu}$ Nucleus Charged Current Interactions

Berge, J.P. ; Bogert, D. ; Endorf, R. ; et al.

Phys.Rev.D 18 (1978) 3905, 1978.

Inspire Record 130082 DOI 10.17182/hepdata.24370

We present data on inclusive negative-hadron production from charged-current antineutrino interactions in a 21% Ne-H mixture. Inclusive single-particle distributions are presented and are shown to be insensitive to the momentum transferred to the hadron vertex. Comparisons made to inclusive data from π−p and π−n interactions indicate a close similarity between the hadrons resulting from π-nucleon and ν¯-nucleus interactions. The general features of the ν¯-nucleus data are found to be similar to those seen in ν¯p interactions. This last observation implies that ν¯p and ν¯n interactions are similar and that nuclear effects are small.

TOTAL ANTI-NEUTRINOS NUCLEON CHARGED CURRENT CROSS-SECTION IN THE ENERGY RANGE 10-GEV - 50-GEV

Asratian, A.E. ; Efremenko, V.I. ; Fedotov, A.V. ; et al.

Phys.Lett.B 137 (1984) 122-124, 1984.

The total v μ N charged current cross section in the energy interval 10–50 GeV is unfolded from 15' bubble chamber antineutrino data. The method is to isolate the quasielastic events and determine their relative contribution to the overall charged current sample. The scale parameter is found to be (0.29 ± 0.03) × 10 −38 cm 2 GeV −1 . Relevance of the method for neutrino oscillation studies is discussed.
