Hybrid Su ( 2 ) × U ( 1 ) Models , Electric Charge Nonconservation and the Photon Mass

چکیده
Hybrid SU (2)×U (1) models are the models in which SU (2)×U (1) symmetry is broken down not only spontaneously (as in the Standard Model), but also explicitely by adding a hard mass term for the U (1) field in the lagrangian. We study the issue of electric charge nonconservation and dequantization in these models. For this purpose we construct and analyze a series of hybrid models with different scalar contents. We show that some of these models posess an interesting property: the photon can remain massless (at least, at the tree level) even though the electric charge is not conserved.

Possible Electric Charge Nonconservation and Dequantization in Su(2)× U(1) Models with Hard Symmetry Breaking
We study a novel type of extensions of the Standard Model which include a hard mass term for the U(1) gauge field and, optionally, the additional scalar multiplets spontaneously violating the electric charge conservation. Contrary to the case of abelian massive electrodynamics, in these theories the massiveness of photon necessarily implies non-conservation (and also dequantization) of the elec...
متن کاملConstraints on the SU(3) Electroweak Model
We consider a recent proposal by Dimopoulos and Kaplan to embed the electroweak SU(2)L × U(1)Y into a larger group SU(3)W × SU(2) × U(1) at a scale above a TeV. This idea is motivated by the prediction for the weak mixing angle sin θW = 1/4, which naturally appears in these models so long as the gauge couplings of the high energy SU(2) and U(1) groups are moderately large. The extended gauge dy...
متن کاملNeutrino Mass and the SU (2)R Breaking Scale
The neutrino sector in a left-right extension of the Standard Model depends on how SU(2)R is broken. I list all possible scenarios, including the ones where the Majorana νR mass is naturally much smaller than the SU(2)R breaking scale, which is desirable for generating the proper baryon asymmetry of the Universe. The best such choice is identified and discussed. In the Standard Model of particl...
متن کاملIs the electric charge conserved in brane world?
We discuss whether electric charge conservation may not hold in four-dimensional world in models with infinite extra dimensions, i.e., whether escape of charged particles from our brane is consistent with effectively four-dimensional electrodynamics on the brane. We introduce a setup with photon localized on the brane and show that charge leakage into extra dimension is allowed within this setu...
متن کاملAbelianization of Low Energy Su(2) Effective Action
Recently Faddeev and Niemi proposed a low energy effective action for pure SU(2) Yang Mills theory in 4 dimension to describe its long distance physics. The effective action is O(3) σ model with a mass parameter, a dimensionless coupling constant e and a topological term. In this work, choosing a new set of variables, we relate this σ model to a U(1) gauge theory with electric and magnetic char...
