In particle physics, little Higgs models are based on the idea that the Higgs boson is a pseudo-Goldstone boson arising from some global symmetry breaking at a TeV energy scale.
[a] The simplified reason for that cancellation is that a loop's contribution is proportional to the coupling constant of one of the SU(2) groups.
This restricts the Higgs boson mass for about one order of magnitude, which is good enough to evade many of the precision electroweak constraints.
Although the idea was first suggested in the 1970s,[1][2][3] a viable model was only constructed by Nima Arkani-Hamed, Andrew G. Cohen, and Howard Georgi in 2001.
[4] The idea was explored further by Arkani-Hamed, Cohen, Thomas Gregoire, and Jay G. Wacker in 2002.
