Prof. dr. Auke-Pieter Colijn

Symposium Arago 2018 Speaker

Auke-Pieter Colijn (1971) is a particle physicist working at the University of Amsterdam and at Nikhef, the Dutch institute for subatomic physics. After completing his PhD he joined the CDF experiment as a Fermilab research associate (Chicago). In 2003 he joined Atlas experiment, where he build the detectors that were later to find the Higgs boson. In 2011 Auke-Pieter joined the XENON collaboration that aims to find the particles that are responsible for most of the matter in our Universe.

We know since many years, that most of the matter in the Universe does not consist of the ordinary atoms that we all know. For every gram of ordinary matter there is about five grams of an as yet unknown substance that we call Dark Matter. In this talk I will describe the astrophysical evidence that makes us believe that Dark Matter exists. Then I will focus on the strategies that we employ to discover new elementary particles that could be Dark Matter, with a focus on the XENON1T and XENONnT experiments in the underground Gran Sasso laboratory in Italy.
