Description
Non-Abelian confinement of quarks in QCD is responsible for 98% of the energy density of visible matter in the Universe whereas the Higgs mechanism is responsible for the remaining 2%. Dark matter has five times the energy density of normal matter so we consider dark matter energy models where non-Abelian confinement of dark quarks also occurs. Dark confinement enables a new feature where dark quarks may be charged under the Standard Model but the only stable dark baryons are electrically neutral and interact only through electromagnetic polarizability. We call the general framework Stealth Dark Matter. Recently, we are particularly interested in a special case called Hyper Stealth Dark Matter where one flavor of dark quarks is particularly light and carry no electric charges as well. We will describe various lattice QFT calculations related to dark matter detection, dark matter self-interaction, and gravity waves from dark confinement transitions in the early universe.
