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
(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 ...
Galaxy Clusters Across the Electromagnetic Spectrum
(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
(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 ...
MIXED AXION-NEUTRALINO DARK MATTER IN THE SUPERSYMMETRIC DFSZ MODEL
(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 ...
ACTIVE GALACTIC NUCLEI IN THE ULTRAVIOLET SPECTRUM
(2016-05-13)
Active Galactic Nucleus (AGN) produce rich, luminescent spectra across the electro- magnetic spectrum. This work focuses on topics in the ultraviolet region, where lie the broad absorption line outflows innate to Broad ...
MICROWAVE AND SURFACE ELECTROMETRY WITH RYDBERG ATOMS
(2016)
Measurements of microwave electric fields in rubidium vapor cells, and of static electric fields near quartz with cold rubidium are presented. The measurements are performed using electromagnetically induced transparency ...
Searches for a high-mass Higgs-like diboson resonance in the H-->WW-->lvqq decay channel using pp collisions at both sqrt(s) = 8 and 13 TeV with the ATLAS detector at the LHC
(2016-08-16)
This work presents two searches for a high-mass Higgs boson in the H-->WW-->lvqq decay channel using the ATLAS detector to analyze the high-energy proton-proton collisions provided by the Large Hadron Collider at two ...
Microwave Electrometry with Rydberg Eletromagnetically Induced Transparency in Vapor Cells
(2016-07-20)
An atom-based approach is presented to detect absolute microwave (MW) electric fields (E-fields). The approach uses Rydberg atoms in vapor cells at room temperature. The MW E-field measurements utilize a bright resonance ...
