Measurement of the tensor Ayy and vector Ay analyzing powers of the deuteron inelastic scattering off berillium at 5.0 GeV/c and 178 mr
Tensor Ayy and vector Ay analyzing powers in the inelastic scattering of
deuterons with the momentum of 5.0 GeV/c on beryllium at an angle of 178 mr in
the vicinity of the excitation of baryonic resonances with masses up to
1.8 GeV/c^2 have been measured. The Ayy data are in a good agreement with the
previous data obtained at 4.5 and 5.5 GeV/c. The results of the experiment are
compared with the predictions of the plane wave impulse approximation and
\omega-meson exchange models.Comment: 18 pages, 9 figure
Search for narrow resonances in e+ e- annihilation between 1.85 and 3.1 GeV with the KEDR Detector
We report results of a search for narrow resonances in e+ e- annihilation at
center-of-mass energies between 1.85 and 3.1 GeV performed with the KEDR
detector at the VEPP-4M e+ e- collider. The upper limit on the leptonic width
of a narrow resonance Gamma(R -> ee) Br(R -> hadr) < 120 eV has been obtained
(at 90 % C.L.)
