Talk title: Dark Sector Cosmology and Naturalness Problems in Particle Physics
Speaker: Yuhsin Tsai
Talk abstract:
Cosmology offers a unique opportunity to explore new physics with tiny interactions to Standard Model particles. I will briefly review two examples where cosmological data is crucial for identifying signals of solutions to particle physics puzzles: (1) The majoron scenario, which explains the hierarchical mass spectrum of neutrinos compared to other fermions and can lead to neutrino decays occurring on a cosmological time scale; (2) the mirror-twin-Higgs model, which addresses the little Higgs hierarchy problem from a well-defined atomic dark matter sector causing dark acoustic oscillation signals in the matter power spectrum.
