Polarization parameters and angular distributions in. pi. /sup + -/p elastic scattering at 100 GeV/cand in pp elastic scattering at 100 and 300 GeV/c

Measurements of the polarization parameters and angular distributions are reported for ${\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}p$ elastic scattering at 100 GeV/c and for $\mathrm{pp}$ elastic scattering at 100- and 300-GeV/c incident momentum. The ${\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}p$ data cover the kinematic range $0.18\ensuremath{\le}\ensuremath{-}t\ensuremath{\le}1.10$ Ge${\mathrm{V}}^{2}$ and are in agreement with current Regge-model predictions. The $\mathrm{pp}$ data cover the kinematic range $0.15\ensuremath{\le}\ensuremath{-}t\ensuremath{\le}1.10$ Ge${\mathrm{V}}^{2}$ and $0.15\ensuremath{\le}\ensuremath{-}t\ensuremath{\le}2.00$ Ge${\mathrm{V}}^{2}$ at 100 and 300 GeV/c, respectively, and are found to be consistent with absorption-model predictions.
