Gedanken Worlds without Higgs
Chris Quigg (Fermilab and Universität Karlsruhe)
Seminar Room 3, 15:00
To illuminate how electroweak symmetry breaking shapes the physical
world, we investigate what the world would be like in the absence of
electroweak symmetry breaking at the usual scale, whether by the
conventional Higgs mechanism or by any of its alternatives, including
dynamical symmetry breaking and higher-dimensional formulations.
Many interesting characteristics of the models stem from the fact that
the effective strength of the weak interactions is much closer to that
of the residual strong interactions than in the real world. The Higgs-free
models not only provide informative contrasts to the real world,
but also lead us to consider intriguing issues in the application of
field theory to the real world.
