Studies in Quantum Field Theory and Astroparticle Physics
Abstract
OVERVIEW OF THE RESEARCH PLAN: Task 1: Theoretical Research in High Energy Physics Prof. Alford investigated the phases and properties of matter at the highest densities achieved in nature. His main focus was on quark matter and its manifestations and signatures in neutron stars. His work is directly relevant to both the Cosmic and the Energy Frontiers. Prof. Bender developed PT-symmetric quantum theory, which is a complex generalization of conventional Hermitian quantum theory. During the grant period, he constructed and analyzed new PT-symmetric field theoretic models that exhibit symmetry breaking. He also worked on other fundamental problems in theoretical physics. His work falls under the Intensity Frontier classification. Prof. Bernard continued to work on lattice gauge theory and associated issues in chiral perturbation theory. His research focused primarily on the calculation of weak matrix elements relevant to tests of the standard model and the search for new physics at the Intensity Frontier. This work included both direct numerical simulations in QCD and the development of theoretical tools to analyze the simulations and facilitate the comparison with Intensity-Frontier experiments. Prof. Ferrer continued working on dark matter and other topics in theoretical particle cosmology. His research focused on weakly interacting massive particles relevant to both the Cosmic and the Energy Frontiers, and on dark photons relevant to the Intensity Frontier. Prof. Ogilvie…
