The topics which will be discussed include:


  Flavour physics

  Neutrino physics

  Precision test of the Standard Model

  Beyond the Standard Model theories and experimental searches

  Astroparticles, Dark matter searches

3. Contributions

The detailed program of the meeting will be established according to the latest experimental and theoretical results at the time of the meeting. Request for contributions should be sent (using the Contribution Form) by email to the appropriate address below, with a copy to the organizer of your choice (by January 15 2005, at the latest). Due to the limited time available, only a restricted number of talks can be accepted.


According to the tradition of the Rencontres de Moriond, a large amount of time will be reserved for both organized and spontaneous discussions. Hence all participants are expected to play an active role during the entire meeting. Please remember that we make a special effort to bring together theorists and experimenters: theoretical talks should be prepared with experimenters in the audience in mind, and experimental talks should likewise be aimed at theorists.

Speakers are kindly requested to write their transparencies in BIG letters and preferably in landscape mode or only using the upper 2/3 of the portrait sheet.
