Abstract: The standard model of particle physics is one of the most robust and best tested theories in the history of physics. However, there are indications that the standard model is incomplete: it has provided no viable candidate for dark matter, no explanation for dark energy or for the dominance of matter over antimatter. New discoveries are therefore necessary to explain these phenomena. Historically, one of the more fruitful avenues for new discoveries in particle physics has been building progressively higher centre of mass energy particle accelerators and sifting trough the massive number of collision products at these accelerators for new particles, this is particle physics at the energy frontier. The most energetic particle accelerator currently operating is CERN’s LHC. In this talk I will discuss particle phenomenology for the LHC’s MoEDAL experiment, specifically MoEDAL's MAPP extension, by discussing one specific candidate particle that may be detectable with MAPP. I will first motivate this proposed new particle by discussing the electric dipole moment of fundamental particles and why this is an interesting probe of important underlying physics, before introducing MAPP’s experimental context and the particular model we used to determine the observability of our candidate. I will conclude by showing the parameter space region where our candidate particle could be detectable by MAPP.
