152. The search for neutrinoless double beta decays with nEXO

Neutrino Properties

Invited Oral

The observed asymmetry between matter and antimatter in the Universe still awaits for an explanation. If lepton number conservation, a global symmetry of the standard model, is violated, that could help understand it. The most sensitive probe to search for this violation is through a hypothetical decay known as neutrinoless double beta decay. Observation of this decay would prove that...

Dark Matter Searches

Contributed Oral

The NEWS-G experiment searches for low-mass dark matter candidates at SNOLAB in Sudbury, Ontario. This direct dark matter search is performed using a spherical proportional counter filled with low atomic mass gases, such as 98% neon + 2% methane. The detector consists of a grounded copper sphere with a high-voltage anode in the centre, which detects ionization within the gas. The inner surface...

114. Machine Learning for Signal Processing in the NEWS-G Experiment

Ms Annabelle Makowski (Queen's University)

Contributed Oral

The NEWS-G experiment at SNOLAB uses spherical proportional counters, or SPCs, to detect weakly interacting massive particles (WIMPs), which are a prime candidate for dark matter. Interactions within the gas-filled sphere create a primary ionization. The signal from the resulting electrons is passed through a digitizer and this generates raw pulses that are observed as time-series data....

129. Search for the X-17 Particle in Montreal

Contributed Oral

The Particle Physics Group at the Montreal Tandem Accelerator is currently working on setting up an experiment to verify the existence of the so-called X-17 particle. This supposed particle of mass 17 MeV/$c^2$ was first claimed to be observed by the ATOMKI experiment in the decays of excited ${}^{8}Be$ and ${}^{4}He$ nuclei to their ground states via internal e+ e- pair creation. The anomaly observed...

98. Search for Low Mass Dark Photons at the Belle II Experiment

Particle Physics

Contributed Oral

The Belle II experiment is operating at the SuperKEKB asymmetric energy electron-positron collider and has accumulated a collision data of 424/fb. This presentation focuses on the search for the dark photon at Belle II. The dark photon is a hypothetical particle that is proposed to serve as a mediator between the Standard Model and dark matter. We search for the production of a dark photon...
