Abstract Details

2021, Doctor of Philosophy, Case Western Reserve University, Physics.
The nature of dark matter remains one of the great unsolved problems in modern cosmology. While we know from indirect observations that dark matter is the dominant form of matter in the Universe, we have yet to detect it directly in laboratory experiments on Earth. Most terrestrial detectors that are discussed in the literature are sensitive only to dark matter candidates with masses well below the Planck scale. In this dissertation we discuss the phenomenology of a generic class of macroscopic dark matter candidates with two parameters, the mass Mx and the geometric cross-section σx which we take to be the interaction cross-section for these objects. The parameter space for such objects is still unexplored over wide ranges of both parameters. We discuss novel approaches to probe more of this parameter space using unconventional detectors. We have also produced world-leading constraints on some regions of this parameter space. At the end of this dissertation, we relax the assumption of a model with only 2 parameters and extend prior work on electrically charged dark matter candidates with masses Mx < 10-13 g to much higher masses. We produce constraints on some regions of the 3 dimensional parameter space based on a variety of null observations on terrestrial, galactic and astrophysical scales. Lastly, we also summarize promising further lines of research to continue exploring more of the parameter space in an effort to conclusively detect the dark matter.
