Boundary correlators of dS bulk fields are important theoretical data for QFT in dS, and are also observables of cosmological collider physics. We will present recent progress in understanding the analytic structure of these inflation correlators with massive exchanges at either tree or loop orders. We will explain why the nonanalyticity of Inflation Correlators is phenomenologically...
I will talk about dark matter in the eV mass range.
The topic includes experimental hints, dark matter theory, and future experimental prospects.
We extend the Standard Model quantum chromodynamics theory (QCD) theory and naturally realize a first-order phase transition at high temperatures above 1 GeV without running into current constraints from both heavy ion colliders and early cosmology. This phase transition is from a non-perturbative effect of the QCD and can have a great impact on the early universe, including gravitational wave...
