The purpose of the Rencontres de Moriond is to discuss recent findings and new ideas in elementary particle physics and other areas of fundamental physics in a pleasant, relaxed and intimate atmosphere. The meeting intends to promote fruitful collaboration between experimentalists and theorists and between various institutions by bringing together a small number of physicists in a beautiful and inspiring atmosphere.


The Moriond Workshop on Energy Densities in the Universe is sponsored by the European Union through the " Training and Mobility of Researchers " program, the French National Center for Scientific Research (CNRS), the US National Science Foundation (NSF), the " Institut de Physique Nucleaire et de Physique des Particules " (IN2P3) and the Atomic Energy Commission (CEA-DAPNIA).

From Bourg-St-Maurice train station to Les Arcs 1800 (Charmettoger):
Buses are available from Bourg-St-Maurice train station to Les Arcs 1800 at most train arrivals from Paris.(1 hour drive) Cost: FF 51 (luggage included). Please ask for a ticket "Les Arcs-Villard". The last one leaves at 19 h 45.
Taxis: approximate fare FF 250 (depending on the number of persons and pieces of luggage).

b) From Geneva Airport to Les Arcs 1800:
With Conference buses: departure from Geneva Airport on Saturday, January 22 at 13h30. Meeting point for the conference bus (a map will be enclosed in Bulletin Nr 2) - Fare: FF 220 one way. Please note that return Conference buses are scheduled to leave Les Arcs on Saturday, January 29 at 12 h 00 sharp (after lunch) and will reach Geneva airport and then CERN around 16 h 30, depending on the traffic.
With regular buses: there are also regular buses from the airport. Time-table not yet communicated. Duration of the drive: about 3 hours, change in Bourg-St-Maurice then take a local bus for Les Arcs 1800. Price: approx. FF 360 one way

c) By car
Les Arcs 1800 can be easily reached by car, by the A43 highway to Albertville, then by the N90 to Bourg-St-Maurice (via Mo×tiers), and then direction Les Arcs 1800 (16 km). If chains are necessary, the sooner you mount them, the better (in Bourg-St-Maurice). In Les Arcs, the temperature can easily go down to - 20 deg. C, so make sure you have sufficient antifreeze.
There are 2 "Hotel Latitudes" in Les Arcs. Be sure that you go to the Latitudes -Charmettoger, at the end of the resort Charmettoger.

9. Miscellaneous

a) The temperature in Les Arcs varies between - 20 and + 5 deg. C. The ground is often icy and it is important to bring suitable walking shoes and warm clothes.
b) An insurance policy, liability and personal accident coverage in Les Arcs has been subscribed to MAIF for the duration of the workshop (sickness is not covered by the insurance).
c) Ski and boot rental is available at the Hotel (special discount for Moriond participants)
d) Please note that your reply to the program committee member who sent you the invitation is not considered as a registration. Registration for your attendance to the workshop and hotel reservation will only be made on receipt of the registration form for which we will acknowledge receipt to each participant.
e) If you fly to Geneva airport and your luggage is missing on your arrival, when making your claim ask for your luggage to be forwarded to you to the Hotel Latitudes-Charmettoger in Les Arcs 1800 by taxi, as quite a few Moriond participants have had their suitcases "stuck" in Bourg-St-Maurice by bus companies.


Please return your registration form as soon as possible. If it is not received by December 1, 1999, we may not be able to get hotel reservation for you.
