Résumé |
In this talk, I will first show that dark QCD model can
realize the idea that all the particle masses can originate from
nonperturbative strong dynamics in the dark sector.
Then I will discuss dark matter of the model, the lightest mesons
and baryons in the dark sector, focusing on the former.
Dark pions could be either WIMP or SIMP DM, depending on the
parameters in the chiral Lagrangian describing the dynamics of
dark pions. In case of the SIMP scenario, I show that including
dark vector mesons can help to realize the SIMP scenario
within the validity region of chiral perturbation theory. |
