Ever since the first measurements were made of these ghostly particles, neutrinos have been a constant fascination for physicists due to their unusual properties. One such peculiarity is that neutrinos can seemingly change flavours as they propagate — a phenomenon known as neutrino oscillation. The oscillation probabilities are determined by a set of fundamental parameters in the Standard...
The nEXO experiment is a proposed neutrinoless double beta decay (0
Silicon photomultipliers (SiPMs) are an excellent solid-state photon detection technology that is becoming increasingly popular in the field of particle and medical physics. The features of SiPMs that make them an ideal candidate for photon detection are their compact size, lightweight, high gain, low operating voltage, low dark noise, and insensitivity to the magnetic field. The nEXO...
The SNO+ experiment is a multi-phase neutrino detector located at the SNOLAB underground physics laboratory in Sudbury, Ontario, Canada. Currently, the 12 m diameter acrylic vessel (AV) is filled with 780 tonnes of the liquid scintillator, linear alkylbenzene (LAB), doped with the fluor 2,5-diphenyloxazole (PPO) to a concentration of 2.2 g/L. The detector is viewed by approximately 9400...
We present results of an analysis studying neutrino-nucleon interactions in the energy range between ~100 GeV - 1 TeV by measuring the inelasticity of these interactions with IceCube DeepCore. IceCube is a Cherenkov neutrino telescope consisting of an optical sensor array placed in ice 1.5 - 2.5 km below the geographic South Pole and covering a volume of roughly 1 km3. DeepCore is a densely...

Precision mass measurements of neutron-deficient
Nuclear pairing, i.e., the tendency of nucleons to form pairs, has important consequences to the physics of neutron star crusts and heavy nuclei. The usual pairing found in nuclei happens between identical nucleons and in singlet states, while recent investigations have shown that certain heavy nuclei might exhibit triplet and mixed-spin pairing correlations in their ground states. In this...
The precision measurements of neutrino oscillation parameters and neutrino-nucleus scattering and also unprecedented sensitivity to physics beyond the Standard Model are the goals of the next generation of long-baseline neutrino experiments. To achieve this high precision and sensitivity, these experiments need a reduction of the uncertainties in neutrino flux calculations. New measurements of...
A high-precision half-life measurement for the radioactive isotope, 26Na, was performed at TRIUMF’s Isotope Separator and Accelerator (ISAC) facility. This is the first experimental test of the high-efficiency Gamma-Ray Infrastructure for Fundamental Investigations of Nuclei (GRIFFIN) spectrometer for performing high precision (± 0.05% or better) half-life measurements [1]. In this talk, I...
The development of the GPD formalism in the last 25 years is a groundbreaking advance in our understanding of the structure of the nucleon. Unifying the concepts of parton distributions and of hadronic form factors, they contain a wealth of new information about how quarks and gluons make up hadrons. For example, GPDs correlate different parton configurations in the hadron at the quantum...
One of the foremost goals of nuclear physics is to provide an understanding of how nuclei are assembled from the basic constituent building blocks of protons and neutrons. Preceding studies have attempted to achieve this by observing the excitation's of nuclei under fine-tuned experimental conditions with the most advanced detectors available on the planet. Nevertheless, this initiative...
