The t-dependence of polarization in pp elastic scattering at all energies

From new measurements in the energy range from T=1.1 to 2.7 GeV becomes evident that t-dependence of polarization P in pp inelastic scattering actually exists already at the lowest energies where the corresponding t-values are permitted by kinematics (t(max) ↔ Θ(CM)=90 deg). This suggests that the explanation should be formulated in a language not specific to the hihg energy region where |t| << s, but applying equally well at much lower energies where the same t-interval corresponds to a large range of CM angles and where |t| is of the same order of magnitude as s. For the s-dependence at fixed t it was well known that the large positive polarization in the first maximum progressively vanishes with increasing s, and that in the dip region the polarization changes to negative values at T ∼ 30 GeV
