The neutron lifetime from beta decay, τ , is a significant value for predictions in particle physics and cosmology. It is used to verify the unitarity of the Cabbibo-Kobayashi-Maskawa (CKM) matrix, the weak force quark mixing matrix in the Standard Model, and for evaluating the abundances of light elements such as Helium-4, created during big bang nucleosynthesis. Furthermore, there is a 3.6 σ...
Cosmological dark matter remains an important unsolved problem in physics. Direct detection using liquid argon offers exciting discovery potential to the “neutrino fog” with sensitivity to spin-independent WIMP-nucleon cross sections below $10^{-48}\,\mbox{cm}^{2}$. A program of phased deployment of ever more sensitive detectors will be described, including the upgraded DEAP-3600 experiment...
In the Fall of 2019, the NEWS-G experiment used its latest detector, a 140 cm diameter Spherical Proportional Counter (SPC) to search for low-mass dark matter at the Laboratoire souterrain de Modane (LSM), in France. SPCs are metallic spheres filled with gas, with a high voltage anode at the centre that attracts and amplifies ionization charges coming from atomic recoils. Having the sphere...
Measurement of the charged-pion branching ratio to electrons versus muons, Re/μ, is extremely sensitive to a wide variety of new physics effects. The precision of the SM prediction for Re/μ is ~1 part in 10^4, 15 times more precise than the current experimental result. A next-generation experiment, PIONEER, is aiming at reducing the precision gap between theory and experiment, testing lepton...
An update of the R&D associated with upgrading the SuperKEKB e+e− collider with polarized electron beams is presented. The Chiral Belle physics program enables a set of unique precision measurements using the Belle II detector. It includes a set of measurements of $\sin^2\theta_W$ via separate left-right asymmetry ($A_{LR}$) measurements in $e^+e^−$ annihilations to pairs of electrons, muons,...
