Chair of Theoretical Elementary Particle Physics (T31)

Academic Career and Research Areas

Dr. van Dyk (*1982) studies the decays of short-lived b (bottom) quarks. Semileptonic b-quark decays in which a lighter quark and two leptons (e.g. electrons or heavier cousins of the electrons) are produced are the focus his studies. The precise properties of these decays can only be infered from experimental measurements with the assistance of theoretical calculations. The group of Dr. van Dyk is tasked to carry out the required calculation. The interpretation of existing and future measurements by the experiments LHCb and Belle II will permit to improve our understanding of elementary interactions at smallest distances. Dr. van Dyk studied physics at the Technische Universität Dortmund, where he got his diploma in 2009, and his PhD in 2012. Subsequently, he was employed as a postdoctoral fellow at the Universität Siegen (2012-2015) and the Universität Zürich (2015-2017). Since 2017 he is a scholar of the Emmy-Noether Programme of the German Research Foundation.
