Virtual Compton Scattering at High EnergyZHANG CHEN In this dissertation we develop a theoretical framework in the context of per-turbative QuantumChromoDynamics (pQCD) for studying non-forward scatteringprocesses. In particular, we investigate a non-forward unequal mass virtual Comptonscattering amplitude by performing the general operator product expansion (OPE)and the for...

Abstract The ratio of central charges in four-dimensional CFT s has been suggested by Hofman and Maldacena to lie within an interval whose boundaries are fixed by the number of supersymmetries. We compute this ratio for a set of interacting N = 1 superconformal field theories which arise as RG fixed points of supersymmetric Yang-Mills theories with adjoint and fundamental matter. We do not find...

We describe some properties of Renormalization Group transformations. Especially we show why some of the RG transformations have redundant eigenoperators with eigenvalues that cannot be determined by simple dimensional analysis and give the corresponding formulae.

We show that superheavy threshold corrections in the New Minimal Supersymmetric GUT based on the SO(10) Higgs system 210 ⊕ 126 ⊕ 126 ⊕ 10 ⊕ 120 can comfortably correct the prediction for the value of α3(MZ) from the relatively large value predicted by the two loop RG equations to the central value determined by the current world average. The unification scale is raised above the one loop value ...

The mass of the Higgs boson in the finely tuned Split Supersymmetric Standard Model is calculated. All 1 loop threshold effects are included, in addition to the full RG running of the Higgs quartic coupling through 2 loops. The 2 loop corrections are very small, typically less than 1GeV. The 1 loop threshold corrections to the top yukawa coupling and the Higgs mass generally push the Higgs mass...

Gentrification has provoked considerable controversy surrounding its effects on residential displacement. Using a unique individual-level, longitudinal data set, this study examines mobility rates and residential destinations of residents in gentrifying neighborhoods during the recent housing boom and bust in Philadelphia for various strata of residents and different types of gentrification. We...

Let G be a finite group having a normal p-subgroup N that contains its centralizer CG(N), and let R be a p-adic ring. It is shown that any finite p-group of units of augmentation one in RG which normalizes N is conjugate to a subgroup of G by a unit of RG, and if it centralizes N it is even contained in N .

The aim of this paper is to present a participatory evaluation of an actual "smart home" project implemented in an independent retirement facility. Using the participatory evaluation process, residents guided the research team through development and implementation of the initial phase of a smart home project designed to assist residents to remain functionally independent and age in place. We r...

Lighthouse Youth Services in Cincinnati, Ohio, began placing foster youth, ages sixteen to eighteen, in individual apartments and other living arrangements in 1981 as a way of preparing them for life after foster care. The program has assisted over thirteen hundred youth and their children using scattered-site apartments, shared homes, roommate situations, host homes, and subsidized housing. Th...
