Scale-genesis by Dark Matter and Its Gravitational Wave Signal

Understand

Classical scale invariance (CSI) may shed light on the weak scale origin, but the realistic CSI extension to the standard model requires a bosonic trigger.

• We propose a scalar Dark Matter(DM) field $X$ as the trigger, establishing a strong connection between the successful radiative breaking of CSI and DM phenomenologies.
• The latter forces the breaking scale to $\sim {\cal O}(\rm TeV)$.
• It brightens the test prospect of this scenario via gravitational wave, a sharp prediction of CSI phase transition (CSIPT), which is first order and has strong supercooling.
