Theoretical Particle Physics at WSU

Question: Discuss the theoretical particle physics at WSU. Answer: According to the ancient Greeks, the universe was composed of fire, air, water and the earth while according to the modern understanding the universe is composed of matter and radiation. Physics assists in the understanding of the universe, due to physics complexity its necessary to apply scale separation to describe as many properties. In the effective field theory, molecular, atomic, nuclear and particle physics are each treated differently. The standard model has been developed throughout the years by a collaborative effort of various scientists it, however, leaves some parameters unexplained making it incomplete. The Higgs mechanism is essential to the standard model in explaining property generation mechanism. Without it, all bosons would be massless contrary to the witnessed phenomenon in CERNs Large Hadron Collider. According to the big bang equal amount of matter and antimatter were created which annihilate each other. The existence of matter then suggests something happened to the antimatter, where did all the antimatter go? The standard model suggests there are three generations of quarks and leptons; this suggestion gives rise to several problems like the origin of mass, strong CP problem and the matter-antimatter symmetry. These problems suggest the need to study Higgs particle or a need for new physics. Evidence like galaxy rotational curves, gravitational lensing, and colliding galaxies all suggest the existence of missing matter; this missing matter must be dark matter which occupies approximately 23% of the mass and energy in the universe. It can be detected through decay patterns and kinematical effects. Theories suggest that dark matter can be produced at the LHC but they would escape unnoticed. Dark matter search in the LHC is considered in the Mono-Higgs channel; it applies the presence of SU(2)L breaking in those operators to avoid the need for any initial-state radiation necessary for the production of invisible particles. This particle theory study at Wayne State was conducted by the faculty, postdocs and graduate students. The faculty was funded by National Science Foundation, US Department of Energy and WSU research and educational grants. Graduate students were funded by NSF Research Assistantships, Three T. Rumble Fellows, and WSU Teaching Assistantships. Academic route, Industry route and Scientific publishing in particle theory can be done after Ph.D.
