Measurement of the Analyzing Power in the Primakoff Process With a High-energy Polarized Proton Beam

The FERMILAB E-704 collaboration Carey, David C. ; Coleman, R.N. ; Corcoran, M.D. ; et al.
Phys.Rev.Lett. 64 (1990) 357, 1990.
Inspire Record 282042 DOI 10.17182/hepdata.19957

The analyzing power (spin-dependent azimuthal asymmetry) has been observed for the first time in the nuclear Coulomb coherent production process, the ‘‘Primakoff process,’’ with the use of the newly constructed 185-GeV/c Fermilab polarized proton beam. We have observed a large asymmetry of this process in the regions of ‖t’‖<0.001 (GeV/c)2 and 1.36<M(π0p)<1.52 GeV/c2, where the Coulomb process is predominant. The measured asymmetry is consistent with the analyzing power of the existing low-energy γ+p→π0+p data.

Observation of significant spin effects in hard collisions at 40-GeV/c

Inspire Record 303587 DOI 10.17182/hepdata.29694

A single-spin asymmetry in the inclusive π 0 production at small x F was measured. In the experiment 40 GeV/c π − mesons were incident on transversely polarized protons and deutrons. An asymmetry of (40–50)% has been revealed in the hard scattering region.

The search for narrow resonances in the reaction e+ e- ---> hadrons at center-of-mass energy range between 7.23-GeV and 10.34-GeV

Z.Phys.C 49 (1991) 239-243, 1991.
Inspire Record 316888 DOI 10.17182/hepdata.15083

The results of a search for narrow resonances ine+e− annihilation at centre-of-mass energies between 7.23 and 10.34 GeV are presented. The experiment was performed using the MD-1 detector at the VEPP-4 storage ring. The total luminosity integral of 16 pb−1 was taken. There is no evidence that new states exist. The upper limits on the leptonic widthΓee of possible resonances are less, by a factor of 10–80, than theΓee for the ϒ(1S) meson.
