Description
Pb-214 β-decay events within a liquid xenon time projection chamber can often look identical to the signature of a WIMP interaction, which causes false positives in the search for dark matter. To combat this, we can “tag” decay events of the Rn-222 decay chain, which is based on the timing and position of decay events. My algorithm pieced these events together like puzzle pieces to determine the validity of Pb-214 β-decay events. Using a Toy Monte Carlo model, I was able to simulate both the Rn-222 decay chain and begin to tag decay events to eliminate false positives.
