The High Energy Physics (HEP) conference of the European Physical Society is the major biannual international event of this research field. With the Int. Conference on High Energy and Particle Physics of IUPAP, held in alternating years, it is the focal place of presenting outstanding experimental and theoretical achievements of the field. European researchers are invited to the conference upon nomination of national contact persons. Non- European (non-EPS member state) physicists can be invited by the organising committee. The Organisers encourage the participation of young pre- and postdoctoral researchers: About one third of the participants, especially from experimental groups belong to the young researcher category. To ensure their participation the conference is divided into two parts: parallel sessions (3 days), dominated by presentations of young researchers followed by 3 days of plenary sessions. Convenors of parallel sessions and keynote speakers are selected by the International Organising Committee, which coincides with the HEPP Committee of EPS. An International Advisory Committee composed of all directors of the major high-energy laboratories in the world, as well as leading theoreticians advises the Committee.
One plenary keynote talk presents highlights of the technological applications stemming form progress in particle physics, with specific emphasis on technology transfer to European companies. An outreach program, including presentation to the general public, will complement this. Films on activities in the field and its implications on daily life will be also presented. The European Prize in high-energy physics is awarded at the opening ceremony of the conference. Its impact is illustrated well by the fact that the 1999 Nobel Prize in physics went to its two previous recipients (M. Veltman (1993) and G. t' Hooft (1999)).
