Bulletin n°1



The XIth International Conference on Elastic and Diffractive Scattering:Towards the High Energy Frontiers will be held in the Château Royal de Blois, France, from Sunday, May 15th, to Friday, May 20th, 2005.
Our conference is the eleventh of the series of the International Conferences on Elastic and Diffractive Scattering, founded in 1985 in Blois. Since that time, meetings were organized in New York, USA (1987), Evanston, USA (1989), Isola d'Elba, Italy (1991), Providence, USA (1993), Blois, France (1995), Seoul, South Korea (1997), Protvino, Russia (1999), Praga, Czech Republic (2001) and Helsinki, Finlande (2003).

In 2005, we will celebrate the twentieth anniversary of the series.

The picturesque old French town of Blois, famous for its XIV-XVIIth century château, is about 170 km (100 miles) from Paris in the beautiful region of the « Châteaux de la Loire ».

The « Rencontres de Blois » are international conferences, whose spirit is explicitly multidisciplinary. They have now been organized for a number of years in the city of Blois, in France, and have covered topics ranging from particle physics to chaos theory, life and planetary science. They are a mix of invited and contributed papers. The present conference is the XVIIth Rencontre de Blois.

The conference will take place in the Château de Blois itself, an ancient Royal residence situated in one of the most charming regions of France; lunch and dinner are served in the castle to all participants; the conference format is designed to encourage discussion and cross-fertilization of ideas. Participants are expected to stay for the whole duration of the Rencontres.
