Measurement of the Spin Rotation Parameter A in the Elastic Pion-proton   Scattering at 1.43 GeV/c
  The ITEP-PNPI collaboration presents new results of the measurements of the spin rotation parameter A in the elastic scattering of negative pions on protons at P_beam=1.43 GeV/c. The results are compared to the predictions of several partial wave analyses. The experiment was performed at the ITEP proton synchrotron, Moscow.
