Fall 2017
We determine the rates, photon energy and angular distributions of positronium decays into a photon and a neutrino-antineutrino pair, $\text{Ps} \to \gamma \nu\ell \bar\nu\ell$. We find that both positronium spin states have access to this decay channel, contrary to a previously published...

Fall 2014
Proper handling of divergent integrals is presented, first with the example of the photon-photon scattering. The classic result of this process was questioned, because the necessity of regularization in the classic calculation was not clear. This challenge has its counterpart. The standard result...

Spring 2023
The decay rate of exotic atoms is of great importance due to their short lifetimes, which presents a challenge when attempting to probe them. The study of pionic atoms can open up a new area of physics, and experiments such as the PiHe collaboration have found a new method of laser spectroscopy...
