I discuss plans and recent R&D progress for a new neutron electric dipole moment (nEDM) experiment to be conducted at TRIUMF. The nEDM is sensitive to CP violation arising from new physics beyond the standard model, and arising in the strong sector of the standard model (the strong CP problem). The experiment at TRIUMF will feature a new superfluid helium source of ultracold neutrons (UCN)...

Cold atoms of antihydrogen present 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. In order to probe matter-antimatter symmetry at the highest possible precision, it is essential that the anti-atoms be suspended in vacuum to allow for detailed...

Potassium-40 (40K) is a background in many rare-event searches, including the DAMA/LIBRA experiment whch claims to have detected the elusive dark matter which may make up most of the matter in the universe. The electron capture of 40K to 40Ar releases ~3 keV X-rays and Auger electrons that fall into DAMA’s region of interest. In most cases, the decay is to an excited state of 40Ar and is...

Following the successful operation of the Large Hadron Collider (LHC)
at collision center-of-mass energy of 7 and 8 TeV in the period
2010-2012, the LHC is now colliding protons at the unprecedented
center-of-mass energy of 13 TeV. Plans are underway to significantly
increase the luminosity of the LHC over the next twenty
years through various upgrades of the accelerator complex. In...

The Twin Higgs model seeks to address the little hierarchy problem by making the Higgs a pseudo-Goldstone of a global $SU(4)$ symmetry that is spontaneously broken to $SU(3)$. Gauge and Yukawa couplings, which explicitly break $SU(4)$, enjoy a discrete $\mathbb{Z}_2$ symmetry that accidentally maintains $SU(4)$ at the quadratic level and therefore keeps the Higgs light. Contrary to most beyond...
