Research Interests

Prof. Cason's research in experimental high energy physics is carried out at Fermi National Accelerator Laboratory (Fermilab) and Brookhaven National Laboratory (BNL). This research is carried out by probing matter through the production of quarks and mesons in high energy collisions.

The research at Fermilab is based on the production of leptons and quarks through proton-antiproton collisions at the D0 experiment. In these interactions, we are interested in searching for evidence for new phenomena which are currently not part of the Standard Model of elementary particle physics. Evidence for anomalous processes is sought in the production of very high mass dimuon pairs as well as very high mass dijets.

At BNL, the search is for exotic mesons – mesons whose internal structure differs from the normal quark-antiquark valence structure of most mesons. Such mesons have now been observed for the first time in our experiments, and we are measuring their properties in order to obtain a deeper understanding of the theory of quantum chromodynamics, the theory describing the strong interaction.
