====== Technicolor ======
 

<tabbox Intuitive> 

Technicolor is the idea that the [[advanced_notions:symmetry_breaking:higgs_mechanism|Higgs boson]] of the [[models:standard_model|Standard Model]] is not a [[advanced_notions:elementary_particles|fundamental particle]] but a composite state of two fermions. These fermions are held together by a new force called Technicolor. The name stems from the idea that this technicolor is similar to the color charge of [[models:standard_model:qcd|quantum chromodynamics]].

<tabbox Abstract>

<tabbox Why is it interesting?> 
Technicolor is a proposed solution for the [[open_problems:hierarchy_puzzle|hierarchy problem]] of the standard model of particle physics.

A great explanation of the motivation behind technicolor models can be found in section V of [[https://www.google.de/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjfu7q0pIDRAhUCuBQKHZJGDPYQFggaMAA&url=http%3A%2F%2Finspirehep.net%2Frecord%2F256768%2Ffiles%2FPages_from_C87-01-24_1-18.pdf&usg=AFQjCNG_zV-CEJmVkkQqYQ8mbiar2QDuCg&sig2=Fu9RQr5VFoq4jeABvdopeg&bvm=bv.142059868,d.d24|The fifth force]] by James D. Bjorken. He draws nicely the analogy between present day Higgs physics and what would have happened if the correct theory of strong interactions were still unknown.
