IS QUARK THE KEY TO THE DARK UNIVERSE?

Presented from Prof Dr Christian Schwanenberger, particle physicist

Everyone knows about the food quark, but the top-quark is an elementary particle and the heaviest one at that. Although it appears to be indivisible and infinitely small, it is about as heavy as an atom of gold, which consists of almost 200 protons and neutrons. These and other striking properties lead many scientists to believe that the top quark could be the key to groundbreaking discoveries such as dark matter. Why is this the case? What is dark matter? And what does all this have to do with quark?

Prof Dr Christian Schwanenberger is Leading Scientist at DESY and Professor at the University of Hamburg. He is member of the CMS Experiment at the Large Hadron Collider (LHC) at CERN in Geneva and of the DZero Experiment at the Tevatron collider in Chicago. His main topics of research are elementary particle physics, in particular precision measurements of the properties of the top quark and its electroweak and strong couplings, the interaction between the top quark and the Higgs boson, searches for supersymmetric and other exotic extensions of the standard model of particle physics, and searches for dark matter.
