VietNam 2006
6th Rencontres du Vietnam
August 6 - 12, 2006

Challenges in Particle Astrophysics

Bulletin Nr 1

The Rencontres du Vietnam began with a meeting in Hanoi on Particle Physics and Astrophysics in December 1993; a second one was held in Saigon in October 1995. The third Rencontres du Vietnam, devoted to Condensed Matter Physics was held in Hanoi in January 1999. The fourth Rencontres du Vietnam, entitled Physics at Extreme Energies, was also held in Hanoi in July 2000. And finally astrophysicists and particle physicists gathered in August 2004 for the fifth Rencontres focused on New Views in Particle Physics and New Views on the Universe.

The aim of the Rencontres has been to extend the successful international collaboration of Europe, Russia, Japan and the United States in these rapidly evolving fields to the emerging Pacific rim countries.

The number of countries represented and the presence of leading scientists has emphasised the importance which the international community places on scientific links with Vietnam.

As a natural continuation of this series, two parallel conferences, one on nanophysics and the other on astroparticle physics, will be organised in 2006.

I. Place and dates

The sixth Rencontres du Vietnam will be held in Hanoi from Sunday August 6th to Saturday August 12th, 2006. It will consist of two parallel conferences held at the same location:

Hanoi, capital of Vietnam, has many universities and research institutes in physics.

II. Purpose of the conference

The conference will be devoted to fundamental and current topics of particle physics and astrophysics from the experimental and theoretical points of view. The aim of the conference is to develop the relationship between Vietnamese physicists and their colleagues all around the world, in particular from South-East Asia and the Western countries.

III. Scientific Organization

The conference is organised jointly by:

IV. Sponsors

Sponsorship has been requested from:
- the French Ministry of Foreign Affairs, Paris, France
- the French National Center for Scientific Research, Paris, France
- the French Atomic Energy Commission, Paris, France
- the Vietnam Academy of Sciences and Technology, Vietnam
- the Asia Pacific Center for Theoretical Physics, Seoul, Korea
- the National Science Foundation, Washington, USA
- the Abdus Salam International Center for Theoretical Physics,Trieste, Italy

V. Scientific program

The scientific program will consist mainly of reviews and invited talks. Parallel and poster sessions will be set up as the need arises; the relevant details may be found on each conference's site. Very schematically, the two conferences will be articulated around a number of key themes (details may be found on other pages on this site, and will be constantly updated):

A. Ultra High Energy Cosmic Rays

B. Dark Matter and Dark Energy

C. Cosmology

D. Neutrinos

E. Gravitational Waves

VI. Conference schedule:

Registration will start on Sunday August 6th in the afternoon. The opening session is scheduled to take place on Monday August 7th at 8:30 and the conference will end on Saturday August 12th, at 12:00.

Session hours are: 8:30 - 12:00 and 13:30 - 17:00

VII. Conference facilities:

The following equipment will be available: a video projector for computer presentations, an overhead projector and a slide projector for 5cm x 5cm slides.

It is hoped that the papers presented at the conference will be published in the form of a proceedings volume. Participants will receive a copy without farther charge.

VIII. Practical organization

Electronic mail

Limited internet access will be available at the conference site. In particular, we anticipate that a wireless hub will be installed.


On-line registration is now available on this site. We would be obliged if you could fill in and return the registration form as soon as possible. Since the conference will be held during the tourist season and hotel rooms are quite limited during that period, room reservation can only be guaranteed if your registration form has reached the conference secretariat by June 30th, 2006.

Conference fee

The conference fee for participants will be 350 US$ or 320 euros. This includes the cost of your copy of the proceedings and the cost of all social events. For the accompanying persons, the conference fee is 100 US$ or 90 euros. It covers the social program as indicated further. Payment can be made either by interbank transfer (preferred method) or by cash at the conference site; we regret that credit card payment will not be possible for the conference fee. Depending on whether you are sending the fee in euros or in dollars, you should transfer the fee to one of the following two banks (and please remember to add 25 euros or 30 $ to cover the bank fees): The transfer should indicate clearly your name to identify the payee. Please inform the conference secretariat by fax or email that the transfer has been done. You should obtain proof of payment, and hand it to the conference secretariat at the conference site. It will take at least 6 weeks for our account to be credited, so please have the transfer made before June 15, 2006.

Social Program

All the participants and their families are invited to the following events: In the case of conference participants, the cost of these events is included in their registration fee.


All sessions of the conference will be held in a five star hotel in Hanoi.

In order to enhance interaction and exchange between participants, we will endeavour to lodge most participants in this same hotel; however, due to limited room availability, some participants will have to be lodged in neighbouring four star hotels, within a short (1km) taxi ride of the conference hotel. Taxis in Hanoi are very cheap and easily available.

If you would in any case prefer to be lodged in one of the four star hotels, please indicate this on the registration form - there is a special line on the form, with a box to be ticked.

All meals, however, will be taken together in restaurants close to the five star hotel (for lunch) or downtown (for dinner).

The cost per person (full board for 6 days) will amount to

Payment for the board and lodging should be done at your arrival directly to the travel agency either by cash, travellers' checks or credit card (the latter will incur a small supplement).

Important note: Hotel reservations are made for the whole duration of the meeting, i.e. from Sunday August 6th afternoon to Saturday August 12th morning (lunch included). Please note that the total cost of the meeting cannot be reduced even in case of partial attendance.

If you intend to arrive before August 6th and leave after August 12th, please let us know in advance, so that we can try to make the appropriate hotel reservation for you.
Please note also that if you arrive before midday, and wish your room to be made available immediately, you will be charged for an extra day; you must inform us, so that the hotel can prepare your room in advance.
