Neutrinoless double-beta ($0\nu\beta\beta$) decay is a beyond-Standard-Model process in which two neutrons decay into two protons and two electrons, without any neutrinos in the final state. If this process is observed experimentally, this would violate lepton number conservation and demonstrate that the neutrino is a Majorana fermion, i.e., its own antiparticle. In order to interpret...
SNO+ is a neutrino detector where the active medium is a liquid organic scintillator (LAB). It is important to understand the backgrounds in detail. C14 is a source of background events in the SNO+ detector. C14 decays can be observed homogeneously throughout the LAB in the detector. The detector is now completely filled with LAB and the process of adding a wavelength shifter (PPO) is ongoing....
Studies of the top quark provide unique insights into the Standard Model due to its large mass. However, the kinematics of $t\bar{t}$ decays is difficult to reconstruct due to the complexity of these events and limited detector resolution. Neural networks are thought to perform as well as state-of-the-art statistical algorithms for reconstruction purposes.
Our group has developed a machine...
Underground at SNOLAB, there are many ongoing experiments, such as SNO+, REPAIR, SuperCDMS etc, that monitor and are extremely sensitive to background radiation. One of the unwanted sources of background radiation that is present at SNOLAB is the naturally occurring radioactive gas, radon-222. Radon decays from Uranium which is found in small amounts in all rocks, and as it further decays into...
The project I am working on is in Simulations and Data Analysis. I am working in the GeRMLab to use machine learning to remove electronic noise from pulses collected with a germanium semiconductor detector. Clean pulses were both simulated and approximated by mathematical functions. Flat noise was added to these pulses, and these, along with noisy pulses from the detector, were used to train,...
