Natural Higgs Mass from Power-Law Running
Kang-Sin Choi
The renormalized scalar mass squared is a function of the energy scale and power-runs as its square. Well above the electroweak scale, its dimensionless couplings evolve only slowl…
One-Loop Correction to the Higgs Mass
Kang-Sin Choi
We present the complete one-loop corrected Higgs mass within the Standard Model. It is crucial to identify the observable mass as the renormalized one that depends on the external…
Stability of the Scalar Mass against Loop Corrections
Kang-Sin Choi
We show that the renormalized loop corrections to the scalar mass are suppressed if the field in the loop is heavy. Here, treating the renormalized mass is important, as it is the…
Renormalization, Decoupling and the Hierarchy Problem
Kang-Sin Choi
The hierarchy problem is associated with renormalization and decoupling. The smallness of the scalar mass against loop corrections follows from the decoupling of heavy fields, once…
On the Observables of Renormalizable Interactions
Kang-Sin Choi
We reconsider the renormalization of scalar mass and point out that the quantum correction to the physical observable, as opposed to the bare parameter, of a renormalizable operato…
