Searching for neutrinoless double-beta decay of germanium-76 in the presence of backgrounds
The neutrino, an elementary particle, has been the subject of experimental investigation for over 50 years. Recent experiments have shown that neutrinos have mass and oscillate, but questions about fundamental properties of the neutrino remain. The observation of neutrinoless double-beta decay could determine whether lepton ...
On the Determination of Elastic and Inelastic Nuclear Observables from Lattice QCD
One of the overarching goals of nuclear physics is to rigorously compute properties of hadronic systems directly from the fundamental theory of the strong interaction, Quantum Chromodynamics (QCD). In particular, the hope is to perform reliable calculations of nuclear processes which would impact our understanding of environments ...
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 ...
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 ...
