16th - 22nd June 2002

Château de Blois (France)


 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 22nd, 2002. 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".

 The Conference is devoted to a multidisciplinary study of matter-antimatter asymmetry and, in particular, from the point 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 project 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:

- Antimatter in the Universe, astronomical and astrophysical constraints, space-based searches, primordial vs. recent antimatter;
- CP violation in particle physics, direct CP violation and rare decays in the K system and critical tests of CP violation in B physics;
- Cosmological matter-antimatter asymmetry, present status of cosmological models, sources of baryon/lepton number violation, out-of-equilibrium situations;
- Antimatter experiments and tests of CPT;
- Experimental and observational prospects, up-coming B physics experiments, dipole moment experiments;
- CP violation in neutrino physics, up-coming measurements of cosmological parameters and of extraterrestrial antimatter abundance.

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

- CP, T and CPT violation;
- CP violation in B mesons;
- Cosmology, baryogenesis and extraterrestrial antimatter;
- Extended models (supersymmetry, Higgs, extra dimensions).

 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 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 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 .


The conference will consist of plenary sessions for invited talks, some parallel sessions for relatively short contributed papers and posters. There will be a coffee break in the middle of the morning and afternoon, lunch and dinner will be served at the Château. The program is as follows: named speakers have confirmed their participation and the titles of their contributions, of course however there may still be unforeseen last minute changes.
