The experimental energy, angular and isotopic distributions for hydrogen and helium nuclei produced in 6.7 GeV deuteron interactions with 58Ni and 64Ni isotopes are presented. The data obtained by using the multichannel E-E semiconductor spectrometer in the 3-50 MeV energy range. Energy spectra are very close to Maxwell distribution, angular distributions are isotropic, isotopic ratios do not depend on emission angle of fragments but depend on a projectile mass

Inclusive Sigma- and Lambda(1520) production in hadronic Z decays.

Production of Sigma- and Lambda(1520) in hadronic Z decays has been measured using the DELPHI detector at LEP. The Sigma- is directly reconstructed as a charged track in the DELPHI microvertex detector and is identified by its Sigma -> n pi decay leading to a kink between the Sigma- and pi-track. The reconstruction of the Lambda(1520) resonance relies strongly on the particle identification capabilities of the barrel Ring Imaging Cherenkov detector and on the ionisation loss measurement of the TPC. Inclusive production spectra are measured for both particles. The production rates are measured to be <N_{Sigma-}/N_{Z}^{had}> = 0.081 +/- 0.002 +/- 0.010, <N_{Lambda(1520)}/N_{Z}^{had}> = 0.029 +/- 0.005 +/- 0.005. The production rate of the Lambda(1520) suggests that a large fraction of the stable baryons descend from orbitally excited baryonic states. It is shown that the baryon production rates in Z decays follow a universal phenomenological law related to isospin, strangeness and mass of the particles.

Single Particle Inclusive Spectra of Charged Particles in anti-p p Interactions at 22.4-GeV/c

Inspire Record 109633 DOI 10.17182/hepdata.35465

The inclusive spectra for p p collisions at 22.4 GeV/ c are investigated. We show that the transverse momentum distributions resemble those in high-energy pp interactions and discuss the influence of annihilation processes on the p T 2 distributions. The invariant inclusive cross section for pions in the central region is found to be 28 ± 1 mb. A charge asymmetry is indicated by the y ∗ spectrum in the central region, the asymmetry parameter having the value 0.15 ± 0.01. Finally, we estimate the upper limit of the diffraction dissociation of the beam particle to be 3.68 −0.15 +0.45 mb.

Photoproduction of $\pi^+$ Mesons from Protons at $E_\gamma = 230$ MeV and Determination of the $\gamma\pi\rho$ coupling Constant

The differential cross section for photoproduction of 1r + mesons from protons at an energy Ey = 230 MeV has been measured for center-of-mass angles of 0, 38, 82, 90, 116, 138, 146, and 180°. A magnetic spectrometer and a meson-stopping detector were used to identify mesons from momentum and range. stopped 1r+ mesons were detected by means of the 1r- p. decay. The statistical accuracy of the results is ±(3-4)% on the average. From comparison of the experimental data with theoretical calculations based on dispersion relations, we have estimated the value of the y1rp coupling constant, Ay1rp = (0.63 ± O.ll)ef.

Inclusive Strange Particle Production in $\pi^+ p$ Interactions at 32-{GeV}/$c$

The production of K s 0 , Λ and Λ is measured in π + p interactions at 32 GeV/ c . The total inclusive cross sections are found to be 2.07±0.14, 1.00±0.10 and 0.14±0.04 mb, respectively. The energy dependence of total inclusive cross sections and inclusive distributions is discussed and a comparison is made with p, p , K + and K − induced reactions. We find that the factorization hypothesis is satisfied for the inclusive reactions π + p→ Λ X and K + p→ Λ X. Multi-strange-particle production is similar in π + p and K + p interactions at 32 GeV/ c . There is evidence for beam fragmentation in Λ production. The hierarchy of Λ inclusive cross sections in p , K + , π + and K − induced reactions at 32 GeV/ c is qualitatively explained by a quark recombination model. The cross sections for inclusive K ∗ + (892) and Σ + (1385) production in 32 GeV/ c π + p interactions are 1.07±0.57 mb and 0.19±0.08 mb, respectively.
