要旨:
We propose a novel possible mechanism to solve the electroweak hierarchy
problem. Assuming the existence of a UV complete underlying fundamental theory
and treating the cutoff scale $\Lambda$ of the effective theory as a real
physical scale we argue that the hierarchy problem would be solved if the
coefficient in front of quadratic divergences vanished for some choice of
$\Lambda$, and if the effective theory mass parameters fixed at $\Lambda$ by
the fundamental theory were hierarchically smaller than $\Lambda$ itself. While
this mechanism most probably cannot work in the Standard Model if the scale
$\Lambda$ is to be close to the Planck scale, we show that it can work in a
minimal extension (Conformal Standard Model) proposed recently for a different
implementation of soft conformal symmetry breaking.
