A Background to Particle Physics

Prof. S. Hannestad, Nordita

Abstract:
Recently the WMAP satellite has provided new data on the cosmic microwave background (CMB) with an unprecedented accuracy. Apart from yielding detailed information about cosmological parameters such as the matter density and the cosmological constant, this data also has direct applications to particle physics. The prime example is the study of neutrino properties using CMB data in conjunction with other cosmological data. In the talk I will review the current observational situation in cosmology, as well as the status of cosmological parameter estimation and its implications for particle physics.
