T he search for physics beyond the standard model—our current best description of fundamental particles and the interactions between them—is a top priority at high-energy particle accelerators. But researchers are also searching for new physics in the “low-energy” environment of the nucleus through a process known as neutrinoless double-beta (0νββ) decay. This hypothetical decay would show that...

Possible models of V·particles, mainly concerned with VO (V10)·particles, are investigated in a systematic way on the basis of their characteristic features, one being experimental evidences and the other theoretical requirements such as the stability of nuclei and the charge independence. The latters play a role for ruling out a proposed decay mode, VO_p + n+ Y, and the single production of ho...

The old Weyl's idea of scale recalibration freedom and the Infeld's and van der Waerden's (IW) ideas concerning geometrical interpretation of the natural spinor phase gauge symmetry are discussed in the context of modern models of fundamental particle interactions. It is argued that IW gauge symmetry can be naturaly identified with U (1) symmetry of Weinberg-Salam model. It is also argued that ...

We describe a geometric picture for the pattern of fermion masses of the three generations which is invariant with respect to the renormalization group below the electroweak scale. Moreover, we predict the upper limit for the ratio between the Dirac masses of the μ and τ neutrinos, ( mνμ/mντ ) ≤ (9.6 ± 0.6) × 10. The Standard Model [1, 2] of strong and electroweak interactions describes accurat...

Dynamical models of inflation are given with composite inflatons by means of massive supersymmetric gauge theory. Nearly flat directions and stable massive ones in the potential are identified and slow-roll during inflation is examined. This kind of dynamical inflations may be ubiquitous in fundamental unified theory with supersymmetry, which should contain gauge theories for interactions of el...

The Standard Model is the theory used to describe the interactions between fundamental particles and fundamental forces. It is remarkably successful at predicting the outcome of particle physics experiments. However, the theory has not yet been completely verified. In particular, one of the most vital constituents, the Higgs boson, has not yet been observed. This paper describes the Standard Mo...

This note is an account of some developments in an effort to find a description of the present stock of elementary particles within the framework of the theory of quantized fields’. The theory of fields suggests that the spin values of $5 for F(ermi)-D(irac) fields, and of 0 and 1 for B(ose)-E(instein) fields are not only exceptional in their simplicity but. are likely to be unique in the possi...

Big Bang Nucleosynthesis (BBN) is one of the most powerful tools to study fundamental interactions since light nuclei abundances crucially depend on many elementary particle properties, like the number of effective neutrino degrees of freedom, Nν . At the moment, however, recent data on Hemass fraction, Y4, and Deuterium (D) and Li abundances, Y2 ≡ D/H and Y7 ≡ 7 Li/H , produced during BBN are ...

Extremely high-energy(EHE) cosmic rays might provide a chance to check a violation of the Lorentz symmetry of spacetime. Some theoretical consideration is described about why the Lorentz symmetry might breakdown in EHE phenomena in this universe. Some models which introduce the violation of the Lorentz symmetry will be discussed. 1 Violation of Symmetry in Actual Universe Great achievement of t...

We discuss possible realizations of the hypothesis that all the fundamental interactions of the elementary particles should be of gauge type, including the Yukawa and Higgs ones. In the minimal SUSY extension of the standard model, where the quartic Higgs couplings are “gauged” through the D-terms, it is also possible to generate radiatively the Yukawa matrices for the light generations, thus e...
