Spring 2019
A bound muon in the presence of a nucleus can decay into an electron, which belongs to either continuous or discrete (bound) energy spectrum. The underlying physics of both cases differ a lot, and so does their importance. The Standard Model decay of a bound muon into an outgoing energetic...

This thesis explores the determination of a few of the fundamental constants of the standard model by employing different methods than those historically used. Modern field theory techniques are applied to the calculation of the α2(Zα)5 corrections to the Lamb shift leading to an increase in the...

Spring 2010
A recent study of the positronium atom showed that the energy levels could be determined numerically using an effective field theory just as easily as the underlying true theory. Here, we expand on this idea by modeling the three-body positronium-ion and four-body di-positronium molecule with...

Spring 2021
This study of bound states composed of short-lived particles (i.e., positron and muon) serves a common purpose to describe their bound properties precisely. The calculation of a scattering amplitude can be lengthy and cumbersome when we have a specific spin preference and many Feynman diagrams....
