A-dependence of the Lambda polarization — •Yury Naryshkin — PNPI RAS Gatchina, Leningrad district 188300, Russia.
The HERMES experiment has measured transverse polarization of Λ and Λ hyperons produced inclusively at positron beam energy 27.6 GeV in quasi-real photon interaction with series of nuclei in a wide range of atomic numbers A ( 1 H,2 D, 3 He, 4 He, 14 N, 20 Ne, 84 Kr and 131 Xe). Dependence of the Lambda polarization on A is studied.
