Fundamental Physical

AbstractElementary interactions are formulated according to the principle of minimal interaction although paying special attention to symmetries. In fact, we aim at rewriting any field theory on the framework of Lie groups, so that, any basic and fundamental physical theory can be quantized on the grounds of a group approach to quantization. In this way, connection theory, although here presented in detail, can be replaced by “jet-gauge groups” and “jet-diffeomorphism groups.” In other words, objects like vector potentials or vierbeins can be given the character of group parameters in extended gauge groups or diffeomorphism groups. As a natural consequence of vector potentials in electroweak interactions being group variables, a typically experimental parameter like the Weinberg angle $$\vartheta _W$$ ϑ W is algebraically fixed. But more general remarkable examples of success of the present framework could be the possibility of properly quantizing massive Yang–Mills theories, on the basis of a generalized Non-Abelian Stueckelberg formalism where gauge symmetry is preserved, in contrast to the canonical quantization approach, which only provides either renormalizability or unitarity, but not both. It proves also remarkable the actual fixing of the Einstein Lagrangian in the vacuum by generalized symmetry requirements, in contrast to the standard gauge (diffeomorphism) symmetry, which only fixes the arguments of the possible Lagrangians.

Higgs Fields

A left–right symmetric model based on graded Lie algebra and noncommutative geometry is constructed. In this approach, the two Higgs fields H R and H L — responsible for the first stage symmetry breaking — transform as [Formula: see text] and [Formula: see text] under SU (2) L , SU (2) R and U(1). Their vacuum expectation values happen to be equal. A bi-doublet ɸ with zero U(1) charge for the second stage is also obtained. Enlarging the Higgs sector with the introduction of the triplets <δ L,R > and singlet <δ0> make parity spontaneously broken at a mass higher than that of the standard charged gauge boson. A fixed value for the Weinberg angle [Formula: see text] and a simple relation between neutral gauge bosons masses [Formula: see text] are predicted.
