This is the first of two companion papers in which we prove that the recently discovery non-perturbative mechanism capable of giving mass to elementary fermions can also generate a mass for the electro-weak bosons, when weak interactions are switched on, and can thus be used as a viable alternative to the Higgs scenario. We can show that the non-pe...

This is the second of two companion papers in which we continue developing the construction of an elementary particle model with no Higgs.

Considerando que para o ensino de física no Ensino Médio adota-se, geralmente, nas escolas públicas o livro didático aprovado pelo Programa Nacional do Livro e Material Didático (PNLD) e que esse pode ser o único referencial para professores e estudantes, ocorreu-nos a seguinte questão: o livro didático pode efetivamente assumir esse protagonismo q...

Information is what tells us about the world. Could we think of physical reality itself as consisting just of information? Could the universe represent over the time the most general collection of logical codes? If we think of information as expressed in terms of binary codes, we could interpret binary sets as spatial arrangements of energy, giving...

By 1933, the class of generally accepted elementary particles comprised the electron, the photon, the proton as well as newcomers in the shape of the neutron, the positron, and the neutrino. During the following decade, a new and poorly understood particle, the mesotron or meson, was added to the list. By paying close attention to the names of thes...

In our universe, distances have increased since the Big Bang. This is directly indicated by the redshift of distant galaxies or of the cosmic microwave background. Usually, that increase of distances is explained by a continuous expansion of space according to general relativity. However, that explanation is very incomplete. This is indicated by th...

The importance of Octahedral Symmetry (Oh) to the results of the Dimensional Gate Operator (DGO) Standard Model is abundantly clear. Octahedral Symmetry links the quaternions to the various Lie Groups and Spin Groups and therefore shows the deep relationship between the DGO conception of the Standard Model and the more conventional approach.

The fundamental symmetries, charge conjugation (C), parity (P) and time reversal (T), play a significant role in the Standard Model (SM) of elementary particle physics. Of these, T symmetry and the combined CP symmetry are the least well understood, and they hold valuable clues for unraveling the secrets of nature. All subatomic particles are postu...
