It was the first meeting on High Energy Experimen- tal Physics in Iran. It was organized and was basically supported financially by the School of Particles and Accelerators of IPM. It marked an important event in the development of physics in our science community; our active and systematic entrance in High Energy Experimental Physics. It also acted as the inauguration of the School of Particles and Accelerators. The meeting covered a wide spectrum of topics of particle physics, especially the physics in LHC. It included reviews and expository lectures by leading physicists of the field as well as seminars on research results by young scientists. The par- ticipation by Iranian young scientists, in particular the experimentalists and phe- nomenologists was substantial. Lectures on topics outside of Particle Physics was organized, e.g. recent developments in observational Astrophysics by Y. Giraud- Hraud. There were about 60 participants, almost half from Iran and half from the rest of the world. Thirty seven talks were delivered, the morning sessions were devoted to reviews and afternoon sessions to recent research results. IPM has tried to establish this field in the country following the agreement be- tween Iran and CMS and signing the MoU to collaborate. This meeting could not take place without the help of our colleagues at CERN in particular Daniel Denegri. He was with us and maybe ahead of us in all stages of the meeting, from the conception of its idea to even the daily schedules of the talks. As a matter of fact his support in our scientific work at cern has been of great effect and value for all of us. On behalf of IPM and the organizers I find this occasion an opportunity to thank him for his help and support. I also want to use the occasion to thank those whose support and help during the past eight years have been instrumental in making our activities possible, Farhad Ardalan, Marc Baarmand, Reza Mansouri, Tiziano Camporesi, Michel Della Negra, Jim Virdee, Galileo Violini, Nural Akchurin. Special thanks are due to Luciano Maiani and John Ellis whose vision and support were essential in the formation of the IPM activities at CERN. The support by CERN and CMS organization in various ways, is gratefully acknowledged. The secretarial team of the meeting has been behind the smooth running of the event, so I would like to extend our appreciation to Mses. A. Arfaee, N. Barati, Z. Ghasemnezhad, H. Alizadeh, N. Nayyeri, P. Kianfar, K. Aspola and Messrs. Aaslanparviz and I. Bagheri. We hope that this meeting will continue and establish a regular event concerning Experimental Particle Physics not only in Iran but also will grow to be a regional activity. I would also like to thank the colleagues in the advisory committee and the local executive committee without whose effort this gathering would not materialize.
