The XIVth Rencontres de Blois, entitled " Matter-Antimatter Asymmetry " will be held at the Château Royal de Blois, France, from Sunday, June 16th to Saturday, June 22th, 2002.


Postal address

Rencontres de Blois, Château de Blois, 41000 Blois, France.

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



This Conference is devoted to a multidisciplinary study of Antimatter, and in particular from the points of view of Particle Physics, Astrophysics and Cosmology. A number of topics, such as the practical applications of antimatter in medical imaging, of particular interest to non-specialists, will also be briefly covered.

More than thirty years after the discovery of CP violation in the kaon system, precision experiments with kaons at CERN and Fermilab have demonstrated the existence of direct CP violation, opening a window on a hitherto poorly explored part of particle physics.

On the one hand, two experiments devoted mainly to CP violation in B mesons, BABAR and BELLE, are beginning to test CP violation in the standard Model in a decisive way.

On the other hand, balloon experiments and the space-based AMS experiment are circumscribing precise limits on the cosmological abundance of antimatter.

Finally, the fundamental problem of cosmological matter-antimatter asymmetry at a Grand Unification scale or at the Electroweak Phase Transition has been the object of intense theoretical activity in recent years.

  • The conference will consist of plenary sessions for invited talks and parallel sessions for relatively short contributed papers. Posters are also welcomed.

    The subjects covered in the plenary sessions will include:

    Four parallel sessions are also foreseen, covering the following topics:

    Details of the scientific program will be made available on the conference web pages as they become available.

    Participants wishing to present their work orally in a parallel session should refer to the conference web site, where they will find an electronic abstract submission form. Please use this form so that we can program the parallel sessions efficiently, since the time available for parallel sessions is very limited; you should indicate the expected duration (maximum : 15 min plus 5 min discussion) of your contribution, but please be aware that you may be required to shorten it.

    Participants wishing to make a poster contribution should also fill in the electronic abstract submission form.
