Manifestations of hidden polarized strangeness of the nucleon in polarization phenomena for the process p +¯p → P0+ V0

The sensitivities of the one-spin and two-spin polarization observables for p+ˉp→P⁰+V⁰, with P⁰=π⁰, η,η′ and V⁰=ρ,ω,φ, based on the triplet enhancement hypothesis for strangeness production in pˉp collisions are analyzed. The analysis is carried out under special kinematical conditions where the P⁰ meson production angle in the CMS is equal to π/2, for which C-invariance of strong interactions reduces the number of independent amplitudes to three.
