Higgs boson; Dark matter

This lecture covers the properties of the Higgs boson, including its mass, decay modes, and interactions with fermions. It also discusses the concept of dark matter, exploring evidence from rotational speeds of stars, gravitational lensing, and cosmic microwave background observations. Different candidates for dark matter, such as WIMPs and sterile neutrinos, are presented, along with detection strategies like direct detection and production at colliders. The lecture emphasizes the importance of collider experiments in understanding the nature of dark matter and highlights the challenges in detecting small signals and distinguishing background noise.
