Title: QCD, Cosmology and Astrophysics
Speaker: Frank Wilczek
Abstract: QCD -- Quantum ChromoDynamics -- is the modern theory of the strong interaction. It allows us to predict with considerable confidence the behavior of matter in various extreme conditions. These include conditions in the very early Universe (extremely high temperature) and in neutron star interiors (extremely high density). Some of the predictions have emerged only recently, and they are striking. They will be tested in experimental `re-creations' of the Big Bang, now taking place at the new Brookhaven RHIC accelerator; and in studies of neutron star and supernova properties, including especially their neutrino emission.
