PERSPECTIVES FOR POLARIZED ANTIPROTONS

n the framework of the FAIR project the PAX Collaboration has suggested new experiments using polarized protons and antiprotons. In order to provide polarized antiprotons, the proposed mechanisms for the production of a polarized stored have to be investigated. To this aim a series of experiments have already been started with protons at the COSY ring. Additional experiment have to be foreseen at AD ring with antiprotons to define to working parameters of a dedicated Antiproton Polarizer Ring
