Extension Of The Lux-Zeplin Nr Background To 600 Phd, Jackson Codd
Extension Of The Lux-Zeplin Nr Background To 600 Phd, Jackson Codd
Macalester Journal of Physics and Astronomy
In June 2022, the LUX-ZEPLIN collaboration released its first results, with the
most precise measurements of any direct dark matter detector. The findings were
calculated using the expected spin-independent WIMP-nucleon interaction model,
which would result in small energies deposited in the detector. Therefore, the
background of non-dark interactions was calculated for events with S1 areas up to
80 phd (Aalbers et al. 2022). In order to increase the sensitivity to high energy
WIMP-nucleon interaction events, as predicted by other models, we extended the
non-dark NR background to events with S1 areas of up to 600 phd. We found a
large …
Model Of Electromagnetic Waves In An Axion-Induced Parity Symmetry Violation, Sarah Lipstone
Model Of Electromagnetic Waves In An Axion-Induced Parity Symmetry Violation, Sarah Lipstone
Macalester Journal of Physics and Astronomy
Axion particles have been postulated to resolve the strong CP problem in Quantum chromodynamics. The axion field may double as the inflaton field that produces cosmic inflation. In this project, we use a combination of analytical and numerical analysis to study how axion-induced parity symmetry violation affects the dynamics of electromagnetic waves.

Searching For Doublet Vectorlike Leptons Using The Atlas Particle Detector, Brynn Keller
Macalester Journal of Physics and Astronomy
Vectorlike leptons are a simple extension of the standard model, akin to a fourth family of leptons. This paper describes aspects of the preparation for a search for VLLs at an ATLAS particle collider. During this research, signal and control regions were determined with use of a Monte Carlo simulation in order to best estimate where to measure different kinds of background and where to search for a potential signal. These signal and control regions were optimized with respect to MET, LT, and number of light and heavy leptons with a goal of a 95\% confidence limit.
