HEP 2015 - Conference on Recent Developments in High Energy Physics and Cosmology 15-18 April 2015, Athens, Greece
Athens. Greece
The HEP2015 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.
