We consider a renormalizable theory, which successfully explains the number of Standard Model (SM) fermion families and whose non-SM scalar sector includes an axion dark matter as well as a field responsible for cosmological inflation. In such theory, the axion gets its mass via radiative corrections at one-loop level mediated by virtual top quark, right handed Majorana neutrinos and SM gauge bosons.

In this paper we consider some properties of the SU(2) Yang-Mills theory connecting with scalar φ4 theory. In the case when scalar field φ is time independent, we find explicit solution to equation of motion for corresponding φ4 theory. The spartial component of the SU(2) Yang-Mills potential corresponding with this solution is like potential of point magnetic monopole.

In this paper we consider some properties of the SU(2) YangMills theory connecting with scalar o4 theory. In the case when scalar field φ is time independent, we find explicit solutions to equations of motion for corresponding o4 theory. The spatial component of the SU(2) Yang-Mills potential corresponding with this solution is like potential of point magnetic monopole.

Scalar field systems containing higher derivatives are studied and quantized by Hamiltonian path integral formalism. A new point to previous quantization methods is that field functions and their time derivatives are considered as independent canonical variables. Consequently, generating functional, explicit expressions of propagators and Feynman diagrams in φ3 theory are found.
