Description
The first results on the polarization of inclusively produced $\Lambda$-hyperons in the $K^{-}$- and $\pi^{-}$-beams and $\bar{\Lambda}$-hyperons in the $\pi^{-}$-beam with a momentum of 26.5 GeV/$c$ were obtained at the SPASCHARM facility at the U-70 accelerator complex in Protvino. For the data on the $K^{-}$-meson beam, a noticeable positive polarization is observed in the region of large values of the Feynman variable $x_F$ and the transverse momentum $p_T$, which was measured for the first time on nuclei. The polarization of $\Lambda$- and $\bar{\Lambda}$-hyperons in the $\pi^{-}$-beam does not exceed several percent in most of the studied kinematic region, with the exception of the region $p_T>1\ \text{GeV}/c$, where the $\Lambda$ polarization is $23\pm 9$ %.
