TARGET ASYMMETRY MEASUREMENT OF DEUTERON PHOTODISINTEGRATION AT A PHOTON ENERGY OF 550-MEV

Althoff, K.H. ; Anton, G. ; Bock, B. ; et al.
Z.Phys.C 26 (1984) 175-179, 1984.
Inspire Record 214987 DOI 10.17182/hepdata.16199

The target asymmetry of the deuteron photodisintegration was measured at a photon energy of 550±50 MeV and at proton center-off-mass angles between 25 and 155 degrees.D-butanol andND3 were used as target material yielding a maximum deuteron polarization of 41%. Proton and neutron were detected in coincidence. The data show a structure which cannot be described by the existing analyses.

Inspire Record 223523 DOI 10.17182/hepdata.20133

The polarization and magnetic moment of the $\Sigma^+$ hyperon have been determined by analyzing 137,300 $\Sigma^+ \to p \pi^0, \pi^0 \to 2 \gamma$ decays. A beam of + inclusively-produced, polarized $\Sigma^+$ hyperons was generated in a Fermilab Meson Lab beamline by 400 GeV protons incident on a beryllium target. The $\Sigma^+$'s were produced at an angle of 5 mrad and ranged in momentum from 140 GeV/c to 350 GeV/c. + 0 The $\Sigma^+ \to p \pi^0, \pi \to 2 \gamma$ decays were detected by a multiwire proportional and drift chamber spectrometer with a lead glass array....

POLARIZATION EFFECTS IN RHO0 MESON PRODUCTION IN ANTI-PROTON PROTON INTERACTIONS AT 22.4-GEV/C, 12-GEV/C, AND 5.7-GEV/C

Batyunya, B.V. ; Boguslavsky, I.V. ; Boos, E.G. ; et al.
Phys.Rev.Lett. 55 (1985) 562-565, 1985.
Inspire Record 221353 DOI 10.17182/hepdata.20274

The ρ0-meson spin alignment is studied in p¯p interactions at 22.4 and 12 GeV/c and in the reaction p¯p→2π++2π−+neutrals at 5.7 GeV/c. An essential ρ0-meson spin alignment is observed. The values of the ρ00T element of the ρ0-meson spin-density matrix in the transversity frame are 0.56 ± 0.07, 0.53 ± 0.05, and 0.54 ± 0.04 for the above-mentioned interactions, respectively. An increase of ρ00T with ρ0 transverse momentum is obtained.

CHARM PRODUCTION IN NEUTRON NUCLEON INTERACTIONS

Tzeng, L. ; Mcbride, P.L. ; Cooper, P.S. ; et al.
Phys.Rev.Lett. 55 (1985) 1172-1175, 1985.
Inspire Record 221439 DOI 10.17182/hepdata.20303

Hadronic production of charmed particles in association with muons from their semileptonic decay has been observed in a high-resolution streamer-chamber experiment performed at Fermilab. A miss-distance analysis of the pictures gives a signal of 17.3±4.7 events. Depending on the production model this corresponds to a range of neutron-nucleon cross sections from 8 to 50 μb, assuming an A23 dependence.

RESULTS FOR NEUTRAL TO CHARGED CURRENT CROSS-SECTION RATIOS FROM neutrino AND anti-neutrino NUCLEUS INTERACTIONS BELOW 30-GeV

Ammosov, V.V. ; Baranov, D.S. ; Ermolaev, V.I. ; et al.
Z.Phys.C 30 (1986) 569, 1986.
Inspire Record 215972 DOI 10.17182/hepdata.15876

Using the freon filled bubble chamber SKAT in the (anti)neutrino wide band beam of the Serpukhov accelerator we determine the neutral to charged current cross section ratios for neutrinos and antineutrinos below 30GeV. From these ratios we calculate in leading order a mixing parameter of the standard model of Θw=0.215±0.029.

LEADING PROTON AND ANTI-PROTON DISTRIBUTIONS IN PROTON NUCLEUS AND ANTI-PROTON NUCLEUS INTERACTIONS

Bailey, R. ; Blanar, G. ; Bosman, M. ; et al.
Z.Phys.C 29 (1985) 1-8, 1985.
Inspire Record 221966 DOI 10.17182/hepdata.15989

We present a study of leading protons and antiprotons inp-nucleus and\(\bar p\)-nucleus on Be, Cu, Ag, W, and U targets. The experiment was performed at the CERN-SPS at a beam energy of 120 GeV. For all targets a suppression of secondary antiprotons with respect to protons is observed. The difference between the\(\bar p\) andp spectra increases with decreasing χ-values and the effect is stronger for heavier nuclei. The features of the data are qualitatively consistent with multiple-collisions modesls. The data are analysed in terms of a dual parton model which gives a satisfactory description of leadingp and\(\bar p\) spectra.
