27. Mediator Decay through mixing with Degenerate Spectrum

Prof. Shigeki Matsumoto (Kavli IPMU, U. of Tokyo)

The decay of the mediator particle into standard model (SM) particles plays a significant role in exploring the dark sector scenario. We consider such a decay, taking the dark photon mediator as an example that mixes with the SM photon. We find that it requires a careful analysis of the decay rate in the presence of an SM vector boson (e.g., Z boson, ρ meson, and true muonium, etc.) nearly...

33. Cosmological Tensions and Inelastical Dark Matter Model

Ki-Young Choi (Sungkyunkwan University)

10/10/2024, 10:00

I will talk about a novel and comprehensive particle physics framework that addresses multiple cosmological tensions observed in recent measurements of the Hubble parameter, S8, and Lyman-α forest data. Our model, termed ‘SIDR+zt’ (Self Interacting Dark Radiation with transition redshift), is based on an inelastic dark matter (IDM) scenario coupled with dark radiation, governed by a U(1)_D...
