Paul Eugenio's research interests are in the areas of particle physics, in particular, on expanding our understanding of the non-perturbative regime of quantum chromodynamics (QCD). While at FSU, Paul Eugenio devoted his efforts to search for meson states, such as, exotics, hybrids, and glueballs, which are incompatible with the Standard Quark Model. He has contributed to an analyses of meson states produced via proton-antiproton annihilations at rest, and he has directed undergraduate students in analyzing meson states from pion-proton interactions at 18 GeV/c. At Jefferson Lab, there is a program which utilizes a state-of-the-art hermetic spectrometer (GlueX) to detect the production and decays of mesons produced in photon-induced reactions. Paul Eugenio has developed a generalized Monte Carlo event generator, a detector simulations package, and a Monte Carlo framework for understanding the performance of key aspects of the proposed GlueX detector systems which is located in Jefferson Lab Experimental Hall D. At FSU, Dr. Eugenio developed and constructed the GlueX Time-Of-Flight (TOF) detector. The GlueX TOF detector is now installed and operational in Jefferson Lab Hall D.
