Residual Non-Abelian Dark Matter and Dark Radiation
P. Ko, Yong Tang
We propose a novel particle physics model in which vector dark matter (VDM) and dark radiation (DR) originate from the same non-Abelian dark sector. We show an illustrating example…
Light dark photon and fermionic dark radiation for the Hubble constant and the structure formation
P. Ko, Yong Tang
Motivated by the tensions in the Hubble constant and the structure growth between results and other low redshift measurements, we discuss some cosmological eff…
A Collider for the 750 GeV Resonant State
Min He, Xiao-Gang He, Yong Tang
Recent data collected by ATLAS and CMS at 13 TeV collision energy of the LHC indicate the existence of a new resonant state with a mass of 750 GeV decaying into two photons $γγ…
Interacting Scalar Radiation and Dark Matter in Cosmology
Yong Tang
We investigate possible cosmological effects of interacting scalar radiation and dark matter. After its decoupling, scalar radiation can stream freely as neutrinos or self-interact…
Pure Gravitational Dark Matter, Its Mass and Signatures
Yong Tang, Yue-Liang Wu
In this study, we investigate a scenario that dark matter (DM) has only gravitational interaction. In the framework of effective field theory of gravity, we find that DM is still s…
