6. Current Status and Prospects of the DEAP-3600 Dark Matter Search

Jie Hu (University of Alberta)

Poster

DEAP-3600 is a single-phase liquid argon (LAr) dark matter detector located 2 km underground at SNOLAB in Sudbury, Canada, searching for nuclear recoils from dark matter scattering in a 3.3-tonne LAr target. In 2019, the collaboration published a leading limit on the WIMP-nucleon spin-independent cross section, based on 231 exposure days. A new profile likelihood ratio analysis extends the...

41. Development of an accelerator-driven Ba-ion source to optimize Barium tagging techniques for a nEXO upgrade

Dwaipayan Ray

Poster

Neutrinoless double-beta decay ($0\nu\beta\beta$) offers a way to probe for physics beyond the Standard Model. Observation of $0\nu\beta\beta$ will validate the Majorana nature of neutrinos, demonstrate violation of lepton number leading to an explanation of the observed baryon asymmetry in the universe, and probe new mass generation mechanisms up to the GUT scale. The planned nEXO experiment...

31. Effective Field Theory Interpretation of Same-Sign WW Vector Boson Scattering with the ATLAS Experiment

Denaisha Kraft

Poster

While the Standard Model (SM) of particle physics has been successful in describing known fundamental particles and interactions, it is incomplete. The amount of charge-parity (CP) violation predicted within the SM is insufficient to explain the observed matter-antimatter asymmetry in the Universe. Additionally, possible deviations in the self-interactions of electroweak bosons motivate the...

69. Improving SNOLAB Radon counting sensitivity with low-background ZnS

Peter Qin (SNOLAB)

Poster

Rn-222 progeny produce unwanted background events in underground rare-event searches including those for dark matter and neutrinoless double beta decay. ZnS(Ag)-coated Lucas cells were used during the SNO experiment to evaluate Radon emanation into light water and continue to be used for ex-situ measurements of Radon concentration in SNO+ and at SNOLAB for materials assays. Support for current...

58. Insight on shape coexistence in $^{100}$Zr through lifetime measurements at GRIFFIN

Konstantin Stoychev (University of Guelph)

Poster

The sudden onset of deformation in $A\approx100$ nuclei at $N=60$ has been described as a ground-state shape transition that has raised a lot of interest over the years from an experimental and theoretical point of view. This transition is most pronounced in the Zr and Sr isotopic chains where the low-energy excited-state structure shows significant signs of deformation developing at $N=60$,...

27. Inverse kinematics measurements of key resonances in 15N(a,g)19F with DRAGON

Aeyla Webster (TRIUMF)

Poster

The origin of the only stable fluorine isotope, $^{19}F$, has remained a longstanding question in nuclear astrophysics due to persistent discrepancies between observations and model-predicted abundances constrained by laboratory reaction rates and nuclear physics input. Recent work by Cristallo et al. highlighted that the reaction rate of $^{15}N(a,g)^{19}F$ – one of the key production...

19. Kaon Structure at Low Photon Virtuality

Abdennacer Hamdi (University of Regina)

Poster

One of the long standing questions in the standard model of particle physics is the origin of nucleon mass, spin, and the charge and density spatial distributions within. In the theory of the strong interaction, the structure of the nucleon is described by form factors which can be accessed through hard exclusive meson production. The main focus of this study is to measure the form factor of...

64. Light Sterile Neutrino Contributions to Neutrinoless Double-beta Decay

Taiki Shickele (TRIUMF/UBC)

Poster

Sterile neutrinos appear in various extensions of the Standard Model and can help explain the origin of the observed active neutrino masses. Light sterile neutrinos in particular can contribute to the neutrinoless double-beta ($0\nu\beta\beta$) decay amplitude, providing an additional avenue to probe new physics, in addition to the established sensitivity of the process to the Majorana nature...

56. R&D and Status of the LED System for Hyper-K’s LED-mPMT Module

Luan Koerich

Poster

The Hyper-Kamiokande (Hyper-K) main detector is under construction and is planned to begin operation in 2027. The detector will consist of a cylindrical water tank measuring 68 metres in diameter and 72 metres in height, instrumented with 20,000 inward-facing 50-cm photomultiplier tubes (PMTs). To enhance calibration capabilities, 800 of the conventional PMTs will be replaced by multi-PMT...

10. Search for Two-Proton Decay from the 6.15 MeV Resonance in 18Ne with ACTAR TPC

Artemis Tsantiri (University of Regina)

Poster

Type I X-ray bursts are among the most frequent thermonuclear explosions we can observe, and can reveal important properties of accreting neutron star systems. Understanding their light curves requires detailed knowledge of the nuclear reactions that enable the transition from the hot CNO cycle towards explosive burning and the rp process. One such key breakout reaction is the 14O(α,p)17F...

57. Spectroscopy of A=100 nuclei with GRIFFIN

Desislava Kalaydjieva (University of Guelph)

Poster

A sudden ground-state shape transition is known to occur sharply at $N=60$, accompanied by equally dramatic changes in the low-energy spectra of the nuclei with A$\approx\!$100. Detailed spectroscopic data on the $\gamma$ decay of $^{100}$Zr are essential for understanding this phase transition and the emergence of shape coexistence, predicted by recent Monte Carlo Shell Model (MCSM)...

68. Status and Prospects of the RadioActive isotope Measurement Program at SNOLAB (RAMPS)

Diba Toyserkani (SNOLAB)

Poster

The RadioActive isotope Measurement Program at SNOLAB (RAMPS) is designed to perform first direct measurement of long-lived nuclear decay processes. The pilot project focuses on performing the first direct measurement of the excited-state electron capture decay of Lutetium-176, a theoretically predicted yet experimentally unobserved nuclear transition. Understanding this highly suppressed...

20. Structure beyond the neutron threshold in N = 50 nuclei using neutron detection techniques at ALTO

Emile Cantacuzene (University of Regina)

Poster

As nuclei get richer in neutrons, the Q-value for beta-decay gets larger while the neutron separation energy decreases. Consequently, for large enough N/Z ratios, the daughter nucleus can decay by emitting one to several neutrons. Directly studying states above the neutron separation energy is an experimental challenge as it requires neutron detectors that have a good energy resolution while...
