Could the Higgs Boson Point Us Toward Dark Matter?
Summary
This episode explores how the Higgs boson may serve as a "portal" to detect elusive dark matter particles. The host explains three detection methods—direct, indirect, and collider-based—before focusing on the Higgs as the most promising avenue for finding invisible matter. By analyzing missing transverse momentum in LHC collisions, physicists can infer the presence of dark matter if the Higgs decays into undetectable particles. The discussion highlights that while current evidence is inconclusive, the new era of Higgs physics offers a vital path toward uncovering the universe's hidden dark …
