Abstract
The spin structure of the amplitudes for antiproton annihilation at rest, [Formula: see text], P=π, η;V=ρ, ω, ϕ, is established. The relation between symmetry properties of strong interaction (isospin invariance and the invariance relative to charge conjugation) and the polarization effects in such reactions are derived. It is demonstrated that the simplest polarization effects in [Formula: see text], namely, the elements of V-meson density matrix, are sensitive to possible violation of the isospin invariance and C-invariance. The analysis of the spin structure of P-wave annihilation amplitudes is also presented.
