CAP Lecture: Dark Matter: How to Hunt for the Unknown

Ken Clark
Queen's University

March 09 2018 at 2:30pm in WMC3260


  • 2:30 - 3:30 PM: Lecture in WMC3260 (coffee and light snacks will be served)
  • 3:30 - 5:00 PM: Informal Q&A Session with Dr. Clark for Undergraduate Students in P8445.2 (pizza and cold beverages will be served)


The quest for understanding the dark matter which pervades our universe has been proceeding for many years and is approaching a momentous time. The existence of this elusive matter is now widely accepted, and considerable experimental effort is directed at deducing its fundamental properties. This talk will focus on results and prospects from two experiments using complementary search techniques. The first is the PICO experiment, a superheated liquid detector at SNOLAB which recently published world-leading results. The second is the IceCube/DeepCore experiment situated in the deep ice at the South Pole and using neutrinos to look for the annihilation signal. Along with the future of these experiments, the imminent challenges to all direct detection experiments will also be discussed.

Short bio:

Prof. Ken Clark

Ken Clark did his PhD work on the PICASSO dark matter search experiment at Queen’s University. He continued to a postdoctoral position at Case Western Reserve University working on the CDMS and LUX projects. This was followed by a diversion into neutrino physics with a UK-centred position located primarily at Oxford University and a return to North America to Pennsylvania State to work on the IceCube experiment. A return to Canada with a position at the University of Toronto provided the opportunity to come back to the dark matter field with PICO, and this involvement continued at SNOLAB. Most recently Ken has accepted a position with CPARC at Queen’s University to continue this work.

About the CAP Lecture

Each year, SFU Physics participates in the Canadian Association of Physicists (CAP) Lecture Tour by inviting a guest speaker to deliver a lecture to SFU undergrad students. The 2018 CAP Lecture Tour will feature presentations that span a wide range of current topics in physics. Lectures will take place between January and April 2018 at participating physics departments in Canada.
