Symmetry Breaking in String Theory
In this paper we discuss symmetry breaking in string theory. Spacetime symmetries are implemented as inner automorphisms of the underlying superconformal algebra. Conserved currents generate unbroken spacetime symmetries. As we deform the classical solutions of the string equations of motion, the deformed currents continue to generate spontaneously broken symmetries eventhough they cease to com...
متن کاملSymmetries and Symmetry-Breaking in String Theory
1. Introduction 1.1. Motivations This note summarizes a talk based on [7]. One motivation for this work is an old and basic question in string theory: What are the fundamental symmetry principles upon which theory should be based. If we understood the answer to this we would then go on to ask how the (on shell) symmetries are broken, and whether there is a notion of a " most symmetric backgroun...
متن کاملHadronic string and chiral symmetry breaking
We assume that QCD can be effectively described with string-like variables. The hadronic string is built over the chirally non-invariant QCD vacuum by means of the boundary interaction with background chiral fields associated with pions. By making this interaction compatible with the conformal symmetry of the string and with the unitarity constraint on chiral fields we reconstruct the equations...
متن کامل" Electroweak Symmetry Breaking through Supersymmetry Breaking "
The connection between the scales of SU(2) × U(1) gauge symmetry breaking and supersymmetry breaking is didactically displayed in the framework of a T.O.Y. (Theory Overestimating Yukawas) model, a version of the (M + 1)SSM (supersymmetric extension of the standard model with a gauge singlet) in which the relevant parameters are determined in the fixed point regime. Some conspicuous features of ...
متن کاملSpontaneous Symmetry Breaking through Mixing
We discuss a model, in which the negative mass square needed in the Higgs mechanism is generated by mixing with a heavy scalar. We have two scalar doublets in the standard model. Phenomenological properties of the heavy new scalar are discussed. The heavy scalar can be detected by the LHC. In the Standard Model (SM) the masses of the Wand Z-bosons and of the fermions (leptons and quarks) are in...
