- 요약The interplay between particle physics models and their cosmological implications provides a crucial set of constraints for model-builders. As upcoming experiments set out to determine the particle nature of dark matter, detect primordial gravitational waves (GWs), and map primordial non-Gaussianities (PNGs), a unique opportunity arises to search for physics beyond the Standard Model (BSM) at scales that may be as high as 1013 GeV. This thesis explores these three examples of cosmological aspects of modelbuilding. We begin with a review of the problems that motivate the search for BSM physics, touching on both the naturalness problems and the inflationary paradigm. Then, we introduce a parity-based solution to the strong CP problem, motivating the question of whether a model containing a heavy mirror copy of the SM gauge group may contain a viable candidate for dark matter. We then turn to GWs, introducing a new source of primordial GWs from stochastic fluctuations of scalar fields in the early universe. Finally, we turn to effective field theories (EFTs) in de-Sitter space, introducing the problem in the context of cosmological collider physics and initiating a systematic understanding of EFT construction in inflationary spacetimes. In turn, we illustrate the promise of near-future cosmological probes to provide insights into the underlying physics of our universe.
