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...
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...
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....
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 $^8Be$ and $^4He$ nuclei to their ground states via internal e+ e- pair creation. The anomaly observed...
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...
