Karlsruhe Tritium Experiment: Detector System Commissioning and In-Situ PIN-Diode Array Dead-Layer Measurement
The <underline>Ka</underline>rlsruhe <underline>Tri</underline>tium <underline>N</underline>eutrino (KATRIN) experimental goal is to measure the neutrino mass to 0.2 eV sensitivity at the 90 percent confidence level. This is an order of magnitude more sensitive than the two most recent direct neutrino mass measurements. The ...
Hubbard Model Approach to X-ray Spectroscopy
We have implemented a Hubbard model based first-principles approach for real-space calculations of x-ray spectroscopy, which allows one to study excited state electronic structure of correlated systems. Theoretical understanding of many electronic features in d and f electron systems remains beyond the scope of conventional ...
Nuclei as Probes of Meson-Nucleon Interactions at High and Low Energy
This dissertation explores two main topics: 1) Color Transparency and quasi-elastic knockout reactions involving pions and &rho mesons; and 2) determination of the J/&psi-nucleon scattering amplitude and scattering length via J/&psi electroproduction on the deuteron. It is shown that at the energies available at the COMPASS ...
