The Lake Louise Winter Institute is devoted to particle physics and the study of fundamental interactions of matter. It is organized by the University of Alberta with support from the Perimeter Institute. It has been held every year since 1986.
The Deep Underground Neutrino Experiment (DUNE) represents a bold step forward with a new detector technology and the ability to measure neutrinos using a broad-band neutrino beam. DUNE will consist of two massive detectors: one located at Fermilab in Illinois, and one located 1300 km away in South Dakota. DUNE offers a unique opportunity to measure the nature of the neutrino masses, quantify the matter-antimatter
symmetry violation, and to potentially discover additional neutrinos. This talk gives an overview of the LBNF-DUNE facility with an emphasis on sensitivity to exotic signatures such as sterile neutrinos and non-standard interactions. The talk also gives an overview of planned Canadian contributions including the data acquisition system, the calibration system and beam line monitor.

Staying tuned for axion dark matter: ADMX Run-1B Results
SuperCDMS SNOLAB Experiment
The SuperCDMS SNOLAB experiment is designed to be a next generation dark matter direct detection experiment, following SuperCDMS Soudan. The experiment is currently under construction. The main science goal is to improve the sensitivity for dark matter particles with masses ≤10 GeV by at least one order of magnitude in cross section over current results from the SuperCDMS Soudan experiment. Two types of cryogenic detectors (HV and iZIP), with germanium and silicon as material, are used to measure the ionization and phonon signals from electron and nuclear recoils of the dark matter. In this talk, I will give a general introduction to the SuperCDMS SNOLAB Experiment, including its history and goals, detector apparatus, signal and background models, as well as the latest sensitivity projection studies and construction progress.
The dawn of PICO-40L
The PICO collaboration uses bubble chambers filled with superheated C3F8 as a target for dark matter detection. PICO-60, with a threshold of 2.45 keV, set the most stringent direct-detection constraint to date on the weakly interacting massive particle (WIMP)-proton spin-dependent cross section at 3.2 × 10−41cm2 for a 25 GeV WIMP [Phys. Rev. D100 022001 (2019)]. Its successor PICO-40L employs a “right-side-up” configuration of the de- tector, thereby eliminating the need for the previously used buffer liquid and enhancing its background rejection capability. PICO-40L also serves as a prototype for another next gener- ation ton-scale chamber PICO-500 which will further explore the WIMP-nucleon parameter space. The commissioning of PICO-40L is nearly complete. Its upcoming run is expected to considerably improve on the previous limit.
