| Abstract: | We have measured the polarization in π? backward elastic scattering at 2.22, 2.46, 2.71 and 3.50 GeV/c incident momenta, in the u-range?1.0 ≦u≦0.1 (GeV/c)2. The experiment used a polarized proton target and detected both pions and protons. We have found large discrepancies between the new data and the result of even the latest phase-shift analysis. |
