Invited Speaker / Conférencier invité
Although the Electroweak Standard Model of Particle Physics has been enormously successful to date, we known it is incomplete. High-precision parity-violating electroweak experiments can provide access to new physics at a wide range of energy scales and play an important complementary role to the LHC research program.
The talk will provide an overview on the past, present and future of...

The n3He experiment aims to measure the parity violating asymmetry in the direction of proton emission from longitudinally polarized cold neutrons capturing on an unpolarized $^3$He target in the reaction $\vec{n}+^{3}He\rightarrow p+T$. The size of the asymmetry is estimated at $(-9.5)- 2.5\times 10^{-8}$. The goal is to measure this asymmetry with an accuracy of $2\times10^{-8}$ to provide...

The NPDGamma experiment has completed a measurement of the parity-violating directional gamma-ray asymmetry in the capture of cold neutrons on protons in a liquid hydrogen target. The asymmetry is directly related to the weak pion-nucleon coupling constant $h^1_{\pi}$, within the framework of the meson exchange model, and it is related to the effective field theory couplings $\tilde C^{\pi}_6$...

Cold antihydrogen promises a unique opportunity to study the properties of atomic antimatter, and via comparisons with its well-studied matter-counterpart, the possibility to test fundamental symmetries such as CPT invariance. We report the first observation of positron spin flip transitions between hyperfine levels of ground state antihydrogen and the first experimental constraint on the...

Matter domination over anti-matter in the universe is not explained by the Standard Model. Extensions to the standard model which could account for this lack of anti-matter introduce larger amounts of CP-violation. If neutrons have larger Electric Dipole Moments (EDMs) than predicted by the standard model, this would indicate one source of CP-violation. To measure the neutron EDM to high...

If a non-zero neutron electric dipole moment (nEDM) were discovered, it would signify a previously unknown source of CP (or T) violation. New sources of CP violation are believed to be required to explain the baryon asymmetry of the universe. The TRIUMF nEDM experiment aims to measure the nEDM to the level $10^{-27}~e\cdot$cm in its initial phase, which is over an order of magnitude more...

The improvement of the electromagnetic calorimeter endcap is the primary hardware contribution of Canada to the Belle-II experiment. The very high luminosity and large associated backgrounds dictate technology improvements required to ensure the performance fulfills the physics needs, despite these backgrounds. Meeting those challenging requirements will be achieved by replacing the crystals...
