- Higgsless model
In
particle physics , a Higgsless model is a model that does not have theHiggs boson , and employs a different mechanism of mass generation andelectroweak symmetry breaking instead.In the years since the Higgs boson was proposed, there have been several alternative mechanisms to the Higgs mechanism. All of the alternative mechanisms use strongly interacting dynamics to produce a vacuum expectation value that breaks electroweak symmetry. A partial list of these alternative mechanisms includes:
*Technicolor [ cite journal | author= S. Dimopoulos and L. Susskind| title=Mass Without Scalars| journal=Nucl.Phys.B| year=1979 | volume=155 | pages=237–252 | doi= 10.1016/0550-3213(79)90364-X] is a class of models that attempts to mimic the dynamics of thestrong force as a way of breaking electroweak symmetry.
