3-3-1 Models at Electroweak Scale
We show that in 3-3-1 models there exist a natural relation among the SU(3)L coupling constant g, the electroweak mixing angle θW , the mass of the W , and one of the vacuum expectation values, which implies that those models can be realized at low energy scales and, in particular, even at the electroweak scale. So that, being that symmetries realized in Nature, new physics may be really just a...
متن کاملInflation at the electroweak scale.
We present a simple model for slow-rollover inflation where the vacuum energy that drives inflation is of the order of G F ; unlike most models, the conversion of vacuum energy to radiation (“reheating”) is moderately efficient. The scalar field responsible for inflation is a standard-model singlet, develops a vacuum expectation value of the order of 4×106GeV, has a mass of order 1GeV, and can ...
متن کاملMonopole Annihilation at the Electroweak Scale—not!
We examine the issue of monopole annihilation at the electroweak scale induced by flux tube confinement, concentrating first on the simplest possibility—one which requires no new physics beyond the standard model. Monopoles existing at the time of the electroweak phase transition may trigger W condensation which can confine magnetic flux into flux tubes. However we show on very general grounds,...
متن کاملBaryogenesis at the Electroweak Scale and above *
We consider origins of the baryon asymmetry which we observe today. We review the progress of electroweak-scale baryogenesis, and show a new mechanism, string-scale baryogenesis. To appear in the Proceeding of the KEK meeting on “CP violation and its origin”. † e-mail address : [email protected], JSPS research fellow.
متن کاملLeading electroweak corrections at the TeV scale
The planned next generation of linear colliders (NLCs) will be able to probe the infrared structure of Standard Model electroweak interactions, that determines the behavior of electroweak radiative corrections at TeV scale energies. I present results of a recent calculation at the leading log level, and discuss my view on open issues and possible future developments of this new and interesting ...
