Higgs naturalness and the scalar boson proliferation instability problem

Understand

Sensitivity to the square of the cutoff scale of quantum corrections of the Higgs boson mass self-energy has led many authors to conclude that the Higgs theory suffers from a naturalness or fine-tuning problem.

• However, speculative new physics ideas to solve this problem have not manifested themselves yet at high-energy colliders, such as the Large Hadron Collider at CERN.
• For this reason, the role of naturalness as a guide to theory model-building is being severely questioned.
• Most attacks suggest that one should not resort to arguments involving gravity, which is a much less understood quantum field theory.
