Λ- hyperon polarization in p-barp-interactions at 32 GeV/c
AbstractAbstract
[en] Λ-hyperon polarization in p-barp -> Λ + Χ, p-barp -> ΛΚ0s + Χ, p-barp -> ΛΛ-bar + Χ reactions at 32 GeV/c is investigated using Mirabelle buble chamber of the Serpukhov accelerator. 5838 events of Λ-hyperon production are analyzed. Dependences of Λ-hyperon polarization on the transfered momenta and Feynmann X-variable are found. Λ-hyperon polarization value in the processes under investigation equals PΛ = -0.16 ± 0.04. 6 refs.; 3 figs
