A Composite Higgs Model with Minimal Fine-Tuning I.~The Large-N and Weak-technicolor Limit

Understand

We suggest a criterion to minimize the amount of fine-tuning in a composite Higgs model.

• The paradigm of this type of model is the top-condensate model of Bardeen, Hill and Lindner (BHL).
• Although "minimally fine-tuned", this model failed to account correctly for the masses of the top quark and the 125~GeV Higgs boson.
• We propose a generalization of the BHL model that employs finely-tuned extended technicolor (ETC) plus technicolor (TC) interactions.
