Baryogenesis Scenarios for Natural Supersymmetric Particle Physics Models
Zhang, Yifan (2019-12-06)Supersymmetric models with radiatively-driven electroweak naturalness require a light higgsino of mass ∼ 100 − 300 GeV. Naturalness in the QCD sector is invoked via the Peccei-Quinn (PQ) axion leading to mixed axion-higgsino ... -
BARYON CONTENT TO THE OUTSKIRTS OF LOW-TEMPERATURE POOR GALAXY GROUPS
Nugent, Jenna (2019-12-05)Little is known concerning the overall properties of galaxy groups, especially at large radii. A better understanding of them will constrain numerical simulations regarding their formation and evolution, as well as reveal ... -
Connections Between the Spectroscopy and Photometry of Type Ia Supernovae
Burrow, Anthony (2024-08-01)Type Ia supernovae (SNe Ia) play a vital role in the study of many topics of astrophysics. They act as cosmological probes through their well-established nature as precise standardizable candles. This nature can be ... -
Cosmology of the PQMSSM
Lessa, Andre (2011)This work presents the main implications of simultaneously considering the Peccei-Quinn solution -

The dark universe: the interplay of cosmological moduli, axions, and the MSSM
Wiley Deal, Robert (2023-05)In this work, we introduce two effective field theories which parameterize a light modulus field interacting both with the MSSM ($\phi$MSSM) and with the MSSM combined with an additional supersymmetric DFSZ axion ($\phi$PQMSSM). ... -
Disentangling the Formation Pathways of Protostars
Reynolds Tran, Nickalas (2023-05)Star formation occurs within dense cores within molecular clouds, often associated with filamentary structures. However, there exist isolated instances of star formation, far from nearby forming stars. As a core collapses, ... -
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 ... -
Fluctuation-induced frictional effects on atoms and nanoparticles
Guo, Xin (2023-08)Fluctuations can cause extraordinary effects on atoms and nanoparticles. For example, a neutral but polarizable particle sitting close to a planar surface feels an attraction force towards the surface. This is the well-known ... -
Interaction Effects in Quantum Wires and One-Dimensional Incoherent Semimetals
Jose, Geo (2022-08-04)In this thesis, we address the effect of interactions in low dimensional systems. In the first part, using bosonization, we study a microscopic model of parallel quantum wires constructed from two dimensional Dirac fermions ... -
J/psi meson production in association with a W boson: Cross section ratio measurement with the ATLAS detector using 8 TeV pp data from the Large Hadron Collider at CERN
Bertsche, David (2016-05-13)The production mechanism of charmonium particles in hadronic collisions is not fully understood and is an active area of research. These mechanisms can be studied by examining the associated production of charmonium particles ... -
Klingen vectors of level 2 for GSp(4)
Yi, Shaoyun (2019-05-10)The theory of Siegel modular forms generalizes classical elliptic modular forms which is, in fact, the degree one case. Dimension formulas for spaces of elliptic modular forms have been much studied, however, the situation ... -
MEASUREMENT OF THE INCLUSIVE ISOLATED PROMPT PHOTON PRODUCTION AT sqrt{s} = 7 TeV WITH THE ATLAS DETECTOR FOR THE 2011 DATASET
Norberg, Scarlet (2014-12)A measurement of the cross section for the inclusive production of isolated prompt photons in $pp$ collisions at a center-of-mass energy $\sqrt{s} = 7\TeV$ is presented. The measurement covers the pseudorapidity ... -
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 and Novel Statistical Methods on the String Landscape
Martinez, Dakotah (2024-08)In this work, we formalize the concept of naturalness in supersymmetric effective field theories, as well as introduce novel methods for performing statistical analyses in the string landscape. We revisit the various ... -
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 ... -
Observation of opposite sign WW with an associated photon production at a center of mass energy of 13 TeV with the ATLAS detector at the LHC
Lambert, Joseph (2022-12)The analysis presented in this thesis expects to provide the first observation of the opposite sign WW with an associated photon process and to measure its fiducial cross section. The analysis uses proton-proton collision ... -
Phenomenology of the String Theory Landscape
Salam, Mohammed Shadman (2022)In this dissertation, we perform a thorough phenomenological study of the string theory landscape. To this end, we compare and contrast the data collected from particle accelerators and detectors against various models of ... -
Probing Flavor Changing Higgs Interactions at LHC and Future Hadron Colliders
Jain, Rishabh (2020-08)In this dissertation, we discuss the prospect of discovering flavor changing neutral Higgs (FCNH) interactions with quarks and leptons at current and future hadron colliders. Particularly, we have looked for $t \to c h^0$ ... -
Radiatively-driven Natural Supersymmetry
Mickelson, Daniel (2014-08-15)Within the framework of supersymmetric theories, a question arises: how can the W, Z, and h masses be so low (∼ 100 GeV) when the superpartner masses are so high (mSUSY > 1−2 TeV)? This is the little hierarchy problem, and ...
