Dimensional Reduction, Monopoles and Dynamical Symmetry Breaking
We consider SU(2)-equivariant dimensional reduction of Yang-Mills-Dirac theory on manifolds of the form M × CP , with emphasis on the effects of non-trivial magnetic flux on CP . The reduction of Yang-Mills fields gives a chain of coupled Yang-Mills-Higgs systems on M with a Higgs potential leading to dynamical symmetry breaking, as a consequence of the monopole fields. The reduction of SU(2)-s...
متن کاملDimensional Reduction and Dynamical Chiral Symmetry Breaking by a Magnetic Field in 3 + 1 Dimensions
It is shown that in 3 + 1 dimensions, a constant magnetic field is a catalyst of dynamical chiral symmetry breaking, leading to generating a fermion mass even at the weakest attractive interaction between fermions. The essence of this effect is the dimensional reduction D → D − 2 (3 + 1 → 1 + 1) in the dynamics of fermion pairing in a magnetic field. The effect is illustrated in the Nambu-Jona-...
متن کاملDimensional Reduction and Catalysis of Dynamical Symmetry Breaking by a Magnetic Field
It is shown that a constant magnetic field in 3+1 and 2+1 dimensions is a strong catalyst of dynamical chiral symmetry breaking, leading to the generation of a fermion dynamical mass even at the weakest attractive interaction between fermions. The essence of this effect is the dimensional reduction D → D − 2 in the dynamics of fermion pairing in a magnetic field. The effect is illustrated in th...
متن کاملDynamical Electroweak Symmetry Breaking
These lectures explored the idea that the physics of electroweak symmetry breaking arises from novel strong dynamics. We started from the familiar strong-interaction dynamics of QCD, introduced simple dynamical electroweak symmetry breaking models whose strong dynamics imitate those of QCD, analyzed the limitations of these models, and finally moved on to theories whose dynamics differ from tho...
متن کاملDynamical Electroweak Symmetry Breaking
We review the status of and recent developments in dynamical electroweak symmetry breaking, concentrating on the ideas of technicolour and top quark condensates. The emphasis is on the essential physical ideas and experimental implications rather than on detailed mathematical formalism. After a general overview of the subject, we give a first introduction to technicolour, and extended technicol...
