L. Bergstrom (Stockholm):


Candidates and Prospects of Detection for Particle Dark Matter



The mystery of what makes up the non-baryonic mass in the universe has deepened. Cosmological measurements tell us with high significance that baryons only make up 4 to 5 percent of critical density, whereas CMB and other measurements point to a total relative matter density of around 30 percent. Although the simplest possibilities like massive neutrinos are ruled out as the main component of dark matter, there are several other, belonging to extensions of the Standard Model which are becoming more and more plausible. Supersymmetric particles are among these favoured candidates, but there are also others based on extra dimensions and other current theoretical ideas. The hunt for dark matter will intensify in the coming years with a large set of accelerator, direct detection and indirect detection experiments each having a fair chance of making the first detection. The talk will cover some of the different particle dark matter candidates and their detection properties.
