Symmetry conserving dynamical mappings

Seniority-conserving forces and USp„2j¿1... partial dynamical symmetry

A quasispin tensor decomposition of the two-nucleon interaction determines the most general seniorityconserving rotationally invariant two-body interaction in a j shell. Such interactions define solvable and partially solvable shell model Hamiltonians for which the unitary symplectic algebra USp(2 j11) provides a complete set of quantum numbers for a subset of states. The matrix elements of sen...

Dynamical 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...

Dynamical 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...

– 1 – Dynamical Electroweak Symmetry Breaking

In theories of dynamical electroweak symmetry breaking, the electroweak interactions are broken to electromagnetism by the vacuum expectation value of a fermion bilinear. These theories may thereby avoid the introduction of fundamental scalar particles, of which we have no examples in nature. In this note, we review the status of experimental searches for the particles predicted in technicolor,...
