Minimal Mirror Twin Higgs

In a Mirror Twin World with a maximally symmetric Higgs sector the little hierarchy of the Standard Model can be significantly mitigated, perhaps displacing the cutoff above the LHC reach. An actual minimal Effective Field Theory construction has constrained and correlated signals in Higgs decays, direct Dark Matter detection and Dark Radiation, all within reach of foreseen experiments over a region of parameter space where the fine-tuning of the electroweak scale is 10-50%.
