Detailed studies of nuclear beta decay can provide stringent tests of the Standard Model of particle physics. In the beta decay of $^{8}$Li, the nucleus emits an electron and an antineutrino, and the daughter $^{8}$Be nucleus is left in an excited state which breaks up into two alpha particles. The angular correlations between these decay products are sensitive to any possible tensor...

The observation of a permanent electric dipole moment (EDM) in a non-degenerate system would indicate violation of time reversal symmetry (T violation) or, equivalently, C(charge)P(parity) violation due to the CPT theorem. The diamagnetic Ra-225 atom is a favorable system in the search for a permanent EDM. This is because the experimental sensitivity to CP violation in radium is enhanced due...

Construction of an Ultra-Cold Neutron (UCN) facility is nearing
completion in the TRIUMF Meson Hall. The new 500 MeV proton
beamline (BL1U) and neutron spallation target, which feeds the
superthermal UCN source, will be completed and transition over
to the commissioning phase in Spring 2016. As well, the front
end of the UCN source will be installed and also undergoing
commissioning...

Our final goal is the measurement of the neutron electric dipole moment with ultracold neutrons (UCN). A new proton beamline for the UCN experiment was recently constructed at TRIUMF. UCNs will be produced by the superfluid He-II UCN source shipped from Japan. For the beam operation, sufficient radiation shields are necessary. We optimized the design of the shields and the layout of the UCN...

We study the effects of custodial symmetry violation in the most general scalar potential of the Georgi-Machacek model (GM). The GM model, which adds isospin triplet scalars to the Standard Model, preserves SU(2) custodial symmetry at tree level by imposing a global SU(2)$_L\times$SU(2)$_R$ symmetry and produces a degenerate fiveplet, a degenerate triplet and two singlet states. Custodial...

The existence of unexpected states (states not predicted by the conventional quark model) in heavy Quarkonia, specifically Charmonium and Bottomonium like states, is of great interest to modern particle physics. States like X(3872), \(Y_{b}\)(10890), \(Z^{\pm}_{b}\)(10610), and \(Z^{\pm}_{b}\)(10650) have proven difficult to reconcile with the conventional quark model. However, analysis of...
