A new type of matter: «dark matter» A dominant enigmatic «substance»: «dark energy» Heavy Elements : 0.03% Neutrinos : 0.3% Stars 0.5% Gas H + HE 4% Dark Matter Dark Energy Michel Spiro, Santiago de Compostella, 20/11/09
The Acceleration of the Universe: dark energy (Supernovae, CMB, BAO ) Examples of type 1a supernovae Thermonuclear detonation of white dwarf High-redshift supernovae are systematically fainter than expected based on extrapolation of low-redshift sources. Must be further away than expected. So need an effect to overcome the tendency of gravity to slow down the expansion.
DARK MATTER Dark matter has already been discovered through Galaxy clusters Galactic rotation curves Weak lensing Strong lensing Hot gas in clusters Bullet Cluster Supernovae CMB, BAO Nucleosynthesis We are entering the decade of dark matter identification (it cannot be ordinary matter)
Origin of mass of elementary particles (neutrinos?) What is the nature of Dark Matter (supersymmetric particles, axions)? What is the nature of Dark Energy (Vacuum energy or space-time curvarure)? Where has all antimatter gone? (study of ultra cold antihydrogen atoms ) Enigmatic neutrinos 8 Random occurrences or new laws?

VACUUM PHASE TRANSITION
Brout, Englert and Higgs mechanism What is vacuum? Full of virtual particles (quantum fluctuations): quasi medium Higgs virtual particles induce vacuum viscosity Vacuum Mexican hat potential shape! Plus existence of a Higgs-particle of mass < 1 TeV, accessible to LHC...

Questions on the HIGGS boson mass: On one hand the Higgs boson has a mass, not only in the allowed range by the Standard Model (below 1 TeV) but at the exact place where the Standard Model can be extrapolated up to 10 15 GeV GUT or inflation scale where it develops some meta stability (inflaton)? On the other hand, quantum corrections to the Higgs mass in the Standard Model would naturally bring the Higgs mass to the inflation scale! Does supersymmetry <10 TeV (no sign yet!!) stabilize the Higgs mass at 126 GeV by cancellations of the corrections? The Higgs boson looks like an ice cube in the fire!

Dark matter. We know neither what the dark energy or the dark matter is A particle relic from the Big Bang is strongly implied for DM WIMPs (Lightest Supersymmetric Particle)? Axions? (an alternative to supersymmetry for dark matter)
1. Particle Dark Matter: supersymmetric neutralinos at GeV to 10 TeV scale Stable, TeV-scale particle, electrically neutral, only weakly interacting No such candidate in the Standard Model Lightest Supersymmetric Particle (LSP): superpartner of a gauge boson in most models LSP a perfect candidate for WIMP CDMS-II Detect Dark Matter to see it is there. Produce Dark Matter in accelerator experiments to see what it is.
Detection of supersymmetric Dark Matter: neutralinos Direct detection CDMS-II, Edelweiss, DAMA, GENIUS, etc Indirect detection SuperK, AMANDA, ICECUBE, Antares, etc complementary techniques are getting into the interesting region of parameter space

Dark matter and Dark Energy Two major evidences for physics beyond the standard model of particle physics and maybe beyond the standard model of cosmology Supersymmetry, axion searches and probing quantum vacuum are the main avenues to tackle these issues Affordable future accelerators together with ultra high intensity lasers will be crucially needed. The future of basic knowledge is at stake.
