The Use Of Operator Regularization In The Computation Of Effective Field Theories, Jeffrey M. Hersh
The Use Of Operator Regularization In The Computation Of Effective Field Theories, Jeffrey M. Hersh
Physics Theses & Dissertations
Current methods of computing low-energy effective field theories while being accurate are extremely cumbersome co implement. Operator regularization provides a way to calculate any desired effective field theory avoiding the tediousness of previous methods. This technique is shown to be an effective method in explicitly calculating the 1/mheavy corrections that match an original full theory to its low-energy effective counterpart. This is demonstrated up to two loop order for the case of a charged two field θ{4}{4} theory as well as up to one loop order for the Higgs sector of the Minimal Supersymmetric Model. Additionally, the renormalization …
Characterization Of Iron Oxides And Atmospheric Corrosion Of Steel, Sei Jin Oh
Characterization Of Iron Oxides And Atmospheric Corrosion Of Steel, Sei Jin Oh
Physics Theses & Dissertations
The study of corrosion behavior was performed using three different analytical techniques, which provided information on the formation, development and layering of iron oxides on the corrosion products as a function of atmospheric conditions, exposure time and type of steel. In particular, the protective layer formed on weathering steel was investigated as a function of different amounts of alloying elements in the steel, atmospheric conditions and exposure times. Combined together, the results provided a better understanding of the atmospheric corrosion behavior of steel, and formed a part of database of the atmospheric corrosion characteristics.
