A Search for Long Lived Neutral Particles Decaying to Hadronic States in Proton-Proton Collisions in the ATLAS Detector at sqrt(s) = 8 TeV and sqrt(s) = 13 TeV at the LHC
A search for the decay of a heavy scalar boson into pairs of long-lived neutral particles in \intlumi of proton proton collisions at $\sqrt{s}=8$~TeV and $3.2~\rm{fb}^{-1}$ at $\sqrt{s}=13$~TeV in the ATLAS detector is ... -
Measuring the Mass of the W Boson with the Last 3.7 fb−1 of Tevatron Data.
This thesis presents the results of an analysis of the $3.7\,\textrm{fb}^{-1}$ of Tevatron proton-antiproton data collected with the DZero (D0) Detector at Fermilab during the ``RunIIb34'' period, with the goal of extracting ... -
Muon-Catalyzed Fusion Effects in the Precision Measurement of Muon Capture on the Deuteron
The MuSun experiment will measure the rate of muon capture on the deuteron to 1.5~\% precision. This reaction is related to solar $pp$ fusion and the $\nu d$ scattering reaction at the Sudbury Neutrino Observatory through ... -
Addressing Beyond Standard Model physics using cosmology
We have consensus models for both particle physics (i.e. standard model) and cosmology (i.e. $\Lambda$CDM). Given certain assumptions about the initial conditions of the universe, the marriage of the standard model (SM) ... -
Electron Detection Systems for KATRIN Detector and Spectrometer Section
A time-of-flight mode is proposed for the upcoming KATRIN experiment beta-decay spectrum measurement, and methods toward the necessary passive detection of a single electron through a large aperture are explored. A sub-fA ... -
Harnessing cell-to-cell variations to probe bacterial structure and biophysics
Advances in microscopy and biotechnology have given us novel insights into cellular biology and physics. While bacteria were long considered to be relatively unstructured, the development of fluorescence microscopy techniques, ... -
Ytterbium and Lithium Quantum Gases: Heteronuclear Molecules and Bose-Fermi Superfluid Mixtures
This dissertation describes a series of experiments conducted in an ultracold mixture of fermionic 6Li and bosonic 174Yb atoms, with a focus on the creation of heteronuclear YbLi molecules and the realization of a mixture ... -
An image segmentation, lineage and analysis tool for bacteria: Applications in cell proliferation and cytoplasmic dynamics.
Because of the stochastic nature and significant cell-to-cell variation of many biological processes, it is essential to analyze a significant number of cells to understand such processes at the single cell level. Such ... -
A Piezoelectrically Tuned RF-Cavity Search for Dark Matter Axions
The Axion is a well motivated hypothetical elementary particle that must exist in nature if the strong CP problem of QCD is explained by the spontaneous breaking of a Peccei-Quinn symmetry. Not only would the discovery of ... -
Ion Photon Entanglement in a Parabolic Mirror Trap
Single trapped ion qubits are excellent candidates for quantum computation and information, and they also possess the ability to coherently couple to single photons. Efficient fluorescence collection is the most challenging ... -
Search for long-lived particles decaying in the muon spectrometer of the ATLAS detector at the LHC
This thesis presents the results of two searches for long-lived, weakly-interacting neutral particles. These searches are performed with 22.1/fb of proton-proton collision data collected with the ATLAS detector at the Large ... -
Toward a Loophole-Free Bell Inequality Violation with Barium Ions
The successful generation of ion-photon entanglement with a singly-trapped Barium ion and the photon it spontaneously emits is reported along with the current progress and technical details for extending this work to a ... -
Optical and Spin Properties of Defect-Bound Excitons in Semiconductors
The physical properties of semiconductor defects are highly relevant for future quantum technologies and current semiconductor device performance. Optical spectroscopy is a powerful tool for investigating a wide variety ... -
Aspects of Chiral Symmetry Breaking in Lattice QCD
In this thesis we describe two studies concerting lattice quantum chromodynamics (LQCD): first, an analysis of the phase structure of Wilson and twisted-mass fermions with isospin breaking effects, second a computational ... -
Device Physics of Two-Dimensional Crystalline Materials
The study of two-dimensional (2D) electrons in condensed matter physics has two milestones: quantum Hall effects in semiconductor heterostructures and superconductivity in cuprates. In both, the 2D electrons are embedded ... -
The role of nuclear physics in supernovae and the evolution of neutron stars, Neutrino Opacities, Equation of State, Transport Coefficients, and Dark Matter Production
A massive star, of at least eight solar masses, end their life cycle in a sudden, catastrophic collapse under its own gravity. In a thousandth of a second, it can shrink from thousands of kilometers across to a ball of ... -
Searches for Beyond Standard Model Higgs Bosons in pp collisions at sqrt(s) = 8 and 13 TeV with the ATLAS detector
The searches for a Beyond Standard Model (BSM) heavy CP-odd Higgs boson $A$ decaying to $Zh$ in the context of two-Higgs-doublet models (2HDM), and Minimal Supersymmetric Standard Model (MSSM) neutral Higgs bosons $H/A$ ... -
Understanding near Fermi-level electronic structure through x-ray emission spectroscopy
Atomic and molecular chemical properties are largely determined by the electronic structure of near Fermi-level states. Determining this structure is therefore one of the central tasks in materials characterization and ... -
Holographic Tools for Probing the Dynamics of Strongly Coupled Field Theories
Since it was conjectured almost 20 years ago, AdS/CFT duality, or holography, has enabled steady progress in understanding certain gauge theories in the strongly coupled limit. In this thesis we examine various aspects of ... -
A search for hep solar neutrinos at the Sudbury Neutrino Observatory
Solar neutrinos from the fusion hep reaction, (helium-3 fusing with a proton to become helium-4, releasing a positron and neutrino), have previously remained undetected due to their flux being about one one-thousandth that ...
