The best way to search for the physics beyond the Standard Model (SM) is by using a diverse set of probes - not just at the energy and the cosmic frontiers, but also the low-energy measurements relying on high precision and high luminosity. Precision tests of the SM, using parity-violating (PV) interaction, gives us possibility to reach the TeV scale, which is complimentary to the LHC searches...

The $\pi\rightarrow e \nu$ branching ratio
$R_\pi= \frac{ \Gamma(\pi\rightarrow e \nu + \pi\rightarrow
e \nu \gamma)}{\Gamma(\pi\rightarrow \mu \nu + \pi\rightarrow \mu \nu \gamma)},$
one of the most precisely calculated weak interaction Standard Model observables involving quarks,
provides a sensitive test of lepton universality and severe constraints on many new physics...

A high intensity UCN source, and an experiment to measure the neutron
Electric Dipole Moment (nEDM) are being developed for TRIUMF. Some new
physics extensions to the standard model predict nEDM VALUES both
above the present limit on the nEDM leading to their abandonment, and
just below the present limit where there are several other model
predictions vulnerable to the same fate. This...

Measuring the neutron Electric Dipole Moment (nEDM) would help answer fundamental cosmological questions like why matter dominated over antimatter even though they are thought to be produced at equal amounts after the Big Bang.
One of the main sources of the systematic uncertainties in the recent nEDM experiments was related to magnetic field fluctuations. For the KEK-RCNP/TRIUMF experiment...

The n3He experiment aims to measure the parity violating asymmetry in the direction of proton emission from the capture polarized cold neutrons in an unpolarized gaseous $^3$He target from the reaction $\vec{n}+^3He\rightarrow T+p$. The size of the asymmetry is estimated to be $(-9.5 \rightarrow 2.5)\times 10^{-8}$, and our goal measurement accuracy is $2\times10^{-8}$. The asymmetry is a...

The knowledge of fundamental properties of the neutron helps us understand many aspect of the universe. It all starts right after the Big Bang: matter wins over antimatter in the Universe, making our existence possible. The main ingredient to that, matter anti-matter asymmetry, requires major violation of another fundamental symmetry, called CP violation. This, in turn might show up in a...
