Unified Interpretation of Scalegenesis in Conformally Extended Standard Models


الملخص بالإنكليزية

We present a universal interpretation for a class of conformal extended standard models including Higgs portal interactions realized in low-energy effective theories. The scale generation mechanism in this class (scalegenesis) arises along the (nearly) conformal/flat direction for the scale symmetry breaking, where the electroweak-symmetry breaking structure is achieved in a similar way to the standard models. A dynamical origin for the Higgs portal coupling can provide the discriminator for the low-energy ``universality class, to be probed in forthcoming collider experiments.
