Flavor Symmetry as a Spontaneously Broken Discrete Permutation Symmetry Embedded in Color
نویسنده
چکیده
A new mechanism for breaking an internal symmetry spontaneously is discussed, which is intermediate between the Nambu-Goldstone and Wigner modes of symmetry breaking. Here the qq̄ sea takes the role of the vacuum of the Nambu-Goldstone case. Flavor symmetry becomes a discrete permutation symmetry of the valence quarks with respect to the sea quarks, which can be spontaneously broken without generation of massless Goldstone bosons.

Model for Particle Masses, Flavor Mixing, and CP Violation, Based on Spontaneously Broken Discrete Chiral Symmetry as the Origin of Families
We construct extensions of the standard model based on the hypothesis that the Higgs bosons also exhibit a family structure, and that the flavor weak eigenstates in the three families are distinguished by a discrete Z6 chiral symmetry that is spontaneously broken by the Higgs sector. We study in detail at the tree level models with three Higgs doublets, and with six Higgs doublets comprising tw...
متن کاملGluons as Goldstone Bosons when Flavor Symmetry is Broken Spontaneously
The mechanism where flavor symmetry of the standard model is broken spontaneously is discussed within a QCD model with effective three-meson couplings. For sufficiently large coupling the model is unstable with respect to quantum loops from mesonic vacuum polarization. It is argued that color and gluons naturally can account for the Goldstone degrees of freedom expected when flavor symmetry is ...

At high density, diquarks could condense in the vacuum with the QCD color spontaneously broken. Based on the observation that the symmetry breaking pattern involved in this phenomenon is essentially the same as that of the Pati-Salam model with broken electroweak–color SU(3) group, we determine the relevant electroweak interactions in the color-flavor locked (CFL) phase in high density QCD. We ...

متن کاملFermion Systems in Discrete Space-Time – Outer Symmetries and Spontaneous Symmetry Breaking
A systematic procedure is developed for constructing fermion systems in discrete space-time which have a given outer symmetry. The construction is illustrated by simple examples. For the symmetric group, we derive constraints for the number of particles. In the physically interesting case of many particles and even more spacetime points, this result shows that the permutation symmetry of discre...
