Preliminary Program
The program of the Vietnam 2006 Conference on
"Challenges in Particle Astrophysics"
is presently under construction.
The general format of the conference is intended to present on
each subject a global introduction / review and then focus on hot
topics. More specialized contributions will also be possible in an
afternoon of parallel sessions:
contributions can be proposed by sending an

A. Ultra High Energy Cosmic Rays
Based on direct measurements on primary cosmic rays, the question
of cosmic ray sources, composition, propagation and acceleration
should be addressed.
- Cosmic Rays, Particle Physics and the High Energy Frontier
- Origin, acceleration and propagation of cosmic rays: the inverse problem
- Composition as a function of energy
- UHECR experiments (precise spectral shape, GZK cutoff?, new physics)
- Uniform source model or exotic sources?
- Shower Properties, Simulation and Detection Techniques
- Intercalibration Fluorescence-Surface Detector
- Radio-detection of HECR
- Observations of HECR from space
- Cosmic Ray hadronic interaction models
- VHE Gamma Ray Astronomy
- Neutrino Astronomy
- Cosmic Rays and Cosmology
B. Dark Matter and Dark Energy
Over the last ten years, precision measurements in cosmology have made it
possible to determine a surprising composition of our Universe. Almost flat
Ωtot ≅ 1.00 +/- 0.02,
our universe appears composed of two
main components, a matter component of density
Ωmat ≅ 0.28, withordinary (baryonic)
matter representing only 4.5% of the universe density, and
a dark energy component
ΩΛ ≅ 0.72. Although
Supersymmetry with conserved R-parity provides a natural candidate with WIMPs
(Weakly Interacting Massive Particles) and the Dark Matter problem, the
situation is more challenging for the Dark Energy component, where a
cosmological constant and a quintessential component both require a high degree
of fine-tuning.
Our global description by the concordance model must then be questioned and
scrutinized to test its relevance. "Challenges in Particle Astrophysics" will
discuss the recent progress in this fascinating field.
