(2017-07-24)This work presents two searches for dark matter at the Large Hadron Collider (LHC). The first is focused on decays of the supersymmetric partner of the top quark, the stop quark (t). By exploiting vector boson fusion (VBF) ...
-
(2010-07-14)We study the nature and clustering of infrared (IR) galaxies at z~1.5-3 in a 9 deg2 region from the Spitzer Deep, Wide-Field Survey (SDWFS) and the MIPS (Multiband Imaging Photometer for SIRTF) AGN (Active Galactic Nuclei) ...
-
(2013-02-01)In searches for new fundamental particles in high energy particle collisions, the ability for a detector to select collisions that might signify the presence of such particles is one of the top priorities. Equally important ...
-
(2022-11-15)Finding the nature of dark matter is one of the biggest quest in physics today. One of the various methods for dark matter detection is direct detection in which the interaction between dark matter and the normal matter ...
-
(2009-05-15)Observations from the 1930s until the present have established the existence of dark matter with an abundance that is much larger than that of luminous matter. Because none of the known particles of nature have the correct ...
-
(2014-04-16)Over 80 years of astrophysical observations suggest that the observable luminous matter makes up ≤ 5% of the total energy density in the Universe. The remaining ~ 95% comes from matter and energy that has not been observed ...
-
(2012-10-19)Dark matter has been shown to be extremely abundant in our universe. It comprises about 23 percent of the energy density of the entire universe, which is more than five times greater than the regular matter we already know ...
-
(2013-07-30)The response of low energy nuclear recoil in NaI(Tl) is investigated in the following experiment. Such detectors have been used recently to search for evidence of dark matter in the form of weakly interacting massive ...
-
(2018-08-08)We study the impact of a modified expansion rate on the dark matter relic abundance and leptogenesis in two types of scalar-tensor theories. The first scenario is motivated from string theory constructions, which have ...
-
(2016-07-29)We study the possibility of detection of the neutralinos and sleptons of the minimal supersymmetric standard model (MSSM) that explains the (g − 2)µ anomaly at the LHC. In this thesis, we scan the MSSM parameter space that ...
-
(2020-03-16)This work is to probe the potential of constraining various parameters of physics beyond Standard Model (BSM) using the coherent scattering of neutrinos from reactors, accelerators, and sun. In this work, a discovery ...
-
(2010-01-14)Galaxies and clusters of galaxies are believed to be dominated by non-luminous non-baryonic dark matter. A favored candidate is a new type of Weakly Interacting Massive Particle (WIMP) with a mass of order 100 GeV/c^2. The ...
-
(2013-02-28)In this dissertation results are presented from a search for the pair production of heavy colored particles (gluinos, squarks) in R-parity conserving supersymmetric models, in which the lightest supersymmetric particle is ...
-
(2020-04-23)Many astrophysical observations indicate that nonbaryonic dark matter makes up around 85% of the total mass content of the Universe. The SuperCDMS experiment represents one of many concerted efforts around the world to ...
-
(2010-10-12)The low-energy supersymmetry phenomenology for specific classes of string compactifications is investigated given that the low-energy physics may provide a clue as to the structure of the fundamental theory at high energy ...
-
(2020-07-22)Observations as early as the 1930s indicated significant disagreements between anticipated gravitational galactic rotations based upon solar luminous intensity and the observed rotations of galaxies. The cause of the ...
-
(2023-04-25)This dissertation is composed of two main research topics: velocity-dependent dark matter (DM) annihilation from simulations, and 3D modeling of the interstellar medium of the Milky Way (MW). The former has been my focus ...
