Abstract

The origin of the baryon asymmetry in the universe and the nature of the dark matter remain mysteries and addressing these cosmological puzzles requires physics beyond the standard model. Electroweak baryogenesis remains a highly testable framework for explaining the baryon asymmetry and is employed in this work to study the capability of baryon generation for beyond standard model physics models and to explore new physics discovery potential in high energy and precision frontier. Weakly interacting massive particles as cold dark matter are also studied in this work featuring loop induced direct detection signals and novel nuclear responses within the recently developed non-relativistic effective field theory framework.
