2009 RENCONTRES DE MORIOND
The XLIVth Rencontres de Moriond were held in La Thuile, Valle d’Aosta, Italy.
The first meeting took place at Moriond in the French Alps in 1966. There, experimental
as well as theoretical physicists not only shared their scientific preoccupations, but also
the household chores. The participants in the first meeting were mainly french physicists
interested in electromagnetic interactions. In subsequent years, a session on high energy
strong interactions was added.
The main purpose of these meetings is to discuss recent developments in contemporary
physics and also to promote effective collaboration between experimentalists and theo-
rists in the field of elementary particle physics. By bringing together a relatively small
number of participants, the meeting helps develop better human relations as well as more
thorough and detailed discussion of the contributions.
Our wishtodevelop andtoexperiment withnewchannels ofcommunication anddialogue,
which was the driving force behind the original Moriond meetings, led us to organize a
parallel meeting of biologists on Cell Differentiation (1980) and to create the Moriond
Astrophysics Meeting (1981). In the same spirit, we started a new series on Condensed
Matter physics in January 1994. Meetings between biologists, astrophysicists, condensed
matter physicists and high energy physicists are organized to study how the progress in
one field can lead to new developments in the others. We trust that these conferences and
lively discussions will lead to new analytical methods and new mathematical languages.
The XLIVth Rencontres de Moriond in 2009 comprised three physics sessions:
•
February 1 - 8: “Very High Energy Phenomena in the Universe”
•
March 07 - 14: “Electroweak Interactions and Unified Theories”
•
March 14 - 21: “QCD and High Energy Hadronic Interactions”
We thank the organizers of the XLIVth Rencontres de Moriond:

We are also grateful to Andrea Righetto, Marcello Torre, Gioacchino Romani and the
Planibel Hotel staff who contributed through their hospitality and cooperation to the
well-being of the participants, enabling them to work in a relaxed atmosphere.
The Rencontres were sponsored by the European Union “Marie Curie Conferences and
Training Courses” Activity, the Centre National de la Recherche Scientifique, The Centre
National d’Etudes Spatiales, the Institut National de Physique Nucl´eaire et de Physique
des Particules (IN2P3-CNRS), the Commissariat `a l’Energie Atomique (DSM and IRFU),
the Fonds de la Recherche Scientifique (FRS-FNRS), the Belgium Science Policy and the
National Science Foundation. We would like to express our thanks for their encouraging
support.
It is our sincere hope that a fruitful exchange and an efficient collaboration between the
physicists and the astrophysicists will arise from these Rencontres as from previous ones.
