Cosmology with a Dark Refraction Index
Chen, Bin (2009)In this dissertation we review Gordon's optical metric theory, generalize it, and apply it to modern cosmology. -

COSMOLOGY WITH TYPE IA SUPERNOVAE: ROBUST TECHNIQUES FOR DATA ANALYSIS AND PHOTOMETRIC CLASSIFICATION
Dai, Mi (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 ... -
Flavor Changing Neutral Currents in a General Two Higgs Doublet Model: Using an Extended Sector to Search for New Physics
McCoy, Brent; McCoy, Phillip (legal first name) (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 ... -
Galaxy Clusters Across the Electromagnetic Spectrum
Griffin, Rhiannon (2016-12)Galaxy clusters are the largest gravitationally bound objects in the Universe. From radio to X-ray, we have observed these objects across the electromagnetic spectrum. Formation theories suggest that clusters even emit ... -
Measurement of the top quark pair production cross section with a tau lepton in the final state at the center of mass energy of 8 TeV
Hasib, Ahmed (2016)This dissertation presents the measurement of the inclusive cross section of the top quark pair production in the final state of a tau lepton with associated jets. The dataset used in this measurement is collected by the ... -
Measuring Cosmological Parameters using Matter Power Spectrum from Galaxy Redshift Survey Data
Maddumage Don, Prasad (2013-12)The galaxy power spectrum is a powerful tool used to study cosmic large scale structure and dark energy. A method to obtain the one dimensional galaxy power spectrum using the direct Fourier method is presented and this ... -
MIXED AXION-NEUTRALINO DARK MATTER IN THE SUPERSYMMETRIC DFSZ MODEL
Serce, Hasan (2016)The lack of evidence for weak scale supersymmetry (SUSY) from LHC Run-I at √s = 8 TeV and Run-II with √s = 13 TeV results have caused a paradigm shift in expected phenomenology of SUSY models. The spectrum of sparticle ... -
Naturalness in Supersymmetry
Padeffke-Kirkland, Maren (2015-06)Weak scale supersymmetry solves the Big Hierarchy problem of the Standard Model. But recent severe sparticle mass limits from the LHC accentuate the Little Hierarchy Problem: Why are the W , Z and h masses so small (∼ 100 ... -
Spectrum Formation at Late Times in Type Ia Supernovae
Friesen, Brian (2015-05-08)I present a study of radiative transfer effects in type Ia supernovae ranging from 3-4 months to nearly 2 years post-maximum light. I explore several components of spectrum formation, beginning with a semi-analytic model ...
