Polarized strangeness in the nucleon

Abstract

A large violation of the Okubo-Zweig-Iizuka rule was discovered in the annihilation of stopped antiprotons. The explanation of these experimental data is discussed in the framework of the model assumed that the nucleon strange sea quarks are polarized.Comment: 10 pages, Latex using espcrc1.sty, Invited talk at Low Energy Antiproton Physics Conference (LEAP 2000), Venice, Italy, August, 200
