Following initial contacts with theoretical physicists at CERN and via experimental collaborations with ALICE groups in Mexico and Italy, senior Cuban physicists visited CERN in 2002 and 2003. They expressed interest in collaboration in medical physics as well as in particle and nuclear physics and Grid computing.
A Cuban institution, the Centro de Aplicaciones Tecnológicas y Desarrollo Nuclear (CEADEN) of La Habana, was accepted into the the ALICE collaboration in 2003.
Cuba participated in the HELEN programme from 2005 to 2009, and some Cuban scientists are currently working at CERN, but the extent of the co-operation is limited in the absence of a Co-operation Agreement. Cuban physicists are now proposing to their authorities a roadmap for greater collaboration with CERN.
