Research ArticleOpen accessIn the keywordsA Brief Review on WIMPs in 331 Electroweak Gauge ModelsP.S. Rodrigues da SilvaIn this study we review the cold dark matter problem in the context of a class of models which are a simple extension of the electroweak standard model, where the gauge symmetry is dictated by the group structure, SU(3)c⊗SU(3)L⊗U(1)X. This model, in different versions, has been able to address many interesting facts not explained by the standard model. It would … …Physics International, Vol. 7, Issue 1 · 27 Oct 2015 · 13,036 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEarly Universe in the SU(3)L⊗U—(1)X Electroweak ModelsHoang Ngoc LongWe present status of the 3-3-1 models and their implications to cosmological evolution such as inflation, phase transitions and sphalerons. The models can deal not only with the issues such as neutrino physics, dark matter, etc, but they are also able to provide quite good agreement with the Standard Cosmology: The inflation happens at the GUT scale, while phase transition … …Physics International, Vol. 7, Issue 1 · 13 Nov 2015 · 7,935 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCRITERIA FOR THE COMPLEXITY OF SUCCESSIVE ASTRONOMICAL PARADIGMSPanagiotis Papaspirou, Kostas Karamanos, Xenophon MoussasWe investigate the complexity of three successive astronomical paradigms in the science of Physics, namely the Ptolemaic paradigm, the Copernican paradigm and the Keplerian paradigm and mention briefly some characteristic facts about the colossal Newtonian paradigm. This complexity can be understood according to five criteria, as proposed by Thomas Kuhn, the father of the epistemological notion of the paradigm, as … …Physics International, Vol. 5, Issue 1 · 28 Mar 2014 · 8,295 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTHE NUMERICAL VALUES OF THE FUNDAMENTAL PARAMETERS OF THE MODEL OF SELFVARIATIONS AND THE AGE OF THE UNIVERSEEmmanuil ManousosThe law of selfvariations determines quantitatively a slight increase of the rest masses and the electric charges of material particles as a common cause of quantum and cosmological phenomena. At cosmological scales the law of selfvariations can be expressed by two similar differential equations for the rest mass and the electric charge respectively. These equations contain information and justify the … …Physics International, Vol. 5, Issue 1 · 20 Mar 2014 · 8,563 accessesView PDF Cite
