SEARCH FOR SUPERSYMMETRY IN FINAL STATES WITH TWO SAME SIGN LEPTONS OR THREE LEPTONS AND JETS WITH THE ATLAS DETECTOR AT THE LHC
(2017-07-07)
The Standard Model of particle physics is the culmination of decades of experimental and theoretical advancements
to successfully describe the elementary particles and their interactions at low energies, up to 100 GeV. ...
Flavor Changing Neutral Currents in a General Two Higgs Doublet Model: Using an Extended Sector to Search for New Physics
(2017-08)
In this dissertation I present studies of flavor-changing neutral Higgs interactions
in a general Two Higgs Doublet Model. I focus on the analytic calculation of
φ → tc and φ → τ μ where φ = h0 , H0 , A0 . In the case ...
COSMOLOGY WITH TYPE IA SUPERNOVAE: ROBUST TECHNIQUES FOR DATA ANALYSIS AND PHOTOMETRIC CLASSIFICATION
(2017-05)
Since the accelerating expansion of the Universe was discovered by observing distant Type Ia supernovae (SNe Ia), SNe Ia have been playing an important role in constraining the unknown cause behind the observed cosmic ...
MOLECULAR BEAM EPITAXY OF ANTIMONY QUANTUM WELLS FOR PROBING TOPOLOGICAL SURFACE STATES
(2017)
A topoelectronic transition was predicted for an Sb quantum well (QW) as a function of QW thickness. Bulk Sb is a semimetal with a negative bandgap, with neither the conduction band minimum nor the valence band maximum at ...
Co-Spatial UV-Optical HST/STIS Spectra of Seven Galactic Planetary Nebulae: Nebular and Stellar Properties
(2017)
This project had two main goals: (1) to investigate to what extent planetary nebulae (PNe) are chemically homogeneous; and (2) to provide physical constraints on the central star properties of each PN. The first goal was ...
Supersymmetry and the Prisoner of Naturalness
(2017-07-27)
In this work, I will address three concerns of supersymmetry. The first is the notion of naturalness and how much fine-tuning exists in a model. Historical measures, ∆ HS and ∆ BG , have led to an over estimate of the ...
