HEP 2014 - Conference on Recent Developments in High Energy Physics and Cosmology 8-10 May 2014, Chora, Island of Naxos, Greece

8 May 2014, 08:00 → 10 May 2014, 23:00 Europe/Zurich

Naxos, Greece

The HEP2014 Conference is organised by the Hellenic Society for the Study of High Energy Physics

The HELLENIC SOCIETY FOR THE STUDY OF HIGH ENERGY PHYSICS (HSSHEP) was founded in 1975. The majority of the Greek scientists (both in Greece and abroad) working in this field are members of the Society. Its main objectives are to promote the scientific work of the Greek scientists and to inform the general public and the Greek state on matters concerning the subject of H.E.P. The Society organizes an annual Workshop where the research activities (both experimental and theoretical) of its members are presented. Young Greek scientists are urged to participate. At the same time foreign collegeaus are invited to cover hot topics. The Society's Executive Committee (Chair, Secretary, Treasurer and two members) is elected during the Annual General Meeting which takes place at the conclusion of the Workshop.
