Dark Matter Updates

New Scientist has been reporting on new ideas about Dark Matter. Apparently, the problems of Dark Matter and the antimatter abundance may be linked. A number of recent conferences discuss the positive results from direct detection experiments, which are seen as evidence for low mass dark matter WIMPs. Slides from a November Princeton workshop are now available online. In the slide below, Kathryn Zurek summarises her analysis with the simplest current explanation: a dark matter mass scale that is five times that of ordinary matter, assuming equal abundances of dark and ordinary particles.
