Measurement of Sigma- Production Polarization and Magnetic Moment

Wah, Y.W. ; Cardello, T.R. ; Cooper, P.S. ; et al.
Phys.Rev.Lett. 55 (1985) 2551-2554, 1985.
Inspire Record 218614 DOI 10.17182/hepdata.42574

We have measured the production polarization of 265- and 310-GeV/c Σ− in the inclusive reaction p+Cu→Σ−+X using 400-GeV/c protons. The polarization was analyzed via the asymmetry in the weak decay Σ−→n+π−, and has typical values of +0.20 with respect to the direction of the cross product of the incident-proton and Σ− momenta. Using the spin-precession technique, we have determined the Σ− magnetic moment to be -1.23±0.03±0.03 nuclear magnetons, where the statistical and systematic errors are shown separately.

The Polarization and Magnetic Moment of the Sigma Plus Hyperon

Wilkinson, Carol Ann ; Pondrom, Lee G. ;
FERMILAB-THESIS-1985-08, 1985.
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....

ASYMMETRY OF pi- MESON EMISSION IN NUCLEUS-NUCLEUS COLLISIONS AS A MEASURE OF THE TARGET TO PROJECTILE RATIO OF THE NUMBERS OF INTERACTING NUCLEONS

Bartke, J. ; Ivanovskaya, I.A. ; Mehdiyev, Rashid R. ; et al.
Z.Phys.C 29 (1985) 9, 1985.
Inspire Record 203310 DOI 10.17182/hepdata.16050

Experimental data on the forward-backward asymmetry of π- emission in (d,4He,12C)181Ta interactions atp/A=4.2 GeV/c are presented. The absolute value of the asymmetry coefficient of the inclusive π- production in the nucleon-nucleonCMS decreases asAp−0.35 with increasing atomic mass of projectile nucleus. A method of obtaining the target-to-projectile ratio of the numbers of participant nucleonsNt/Np through measuring the velocity of the symmetric pion emission system is proposed. It has been found that Nt/Np∼Ap−0.73.
