Vector mesons in Friedman space-time

Particle creation of vector mesons in nonstationary Friedman space-time is investigated by the method of diagonalizing the instantaneous Hamiltonian. The density of particles and the full stress-energy tensor are calculated. Reasons are given for the Higgs treatment of vector mesons in gravitational field creating pairs of particles.     

Fields with continuously distributed mass

We describe local field theories with continuously distributed mass. Such models can be realized as models in d > 4 space-time with Poincare invariance only in four-dimensional space-time. We also discuss some possible phenomenological consequences. Namely, we show that the Higgs boson phenomenology in the SM extension with continuously distributed Higgs boson mass can differ in a drastic way from the standard Higgs boson phenomenology.     

Conformal invariance and the Higgs boson mass in the Weinberg-Salam theory with gravitational mechanism of instability

The assumption that the Higgs scalar field equation is conformally invariant leads to new features of the unified gauge theories including classical gravitation. Both the self-consistent approach and the external curved space-time method are discussed here. The purpose is to compute the upper and lower bounds on the mass of the stable Higgs particle. Also an attempt to obtain a discrete mass spectrum at classical level was made.     

Spherical symmetry of generalized EYMH fields

The possible actions of symmetry groups on generalized Higgs fields coupled to an Einstein–Yang–Mills field are studied with differential geometrical techniques involving principal and associated bundles. A classification of conjugacy classes of these actions and the form of the corresponding invariant Einstein–Yang–Mills–Higgs (EYMH) fields is obtained and then applied to the case of static spherically symmetric fields over four-dimensional space-time. We identify the representations of the gauge group for which spherically symmetric Higgs fields exist. Then the set of all field equations for the independent functions that describe these fields is analyzed and the corresponding ordinary system of differential equations is derived and shown to be consistent.     

Magnetic monopole in the general theory of relativity

Equations of motion are obtained for Yang-Mills and Higgs fields using the Georgi-Glashow SO(3)-model in a curved spherically symmetric space-time. Magnetic monopole and dion solutions and the space-time metric are found in the intrinsic gravitational field. A particlelike solution of the magnetic monopole and dion type is constructed in the external field of a static universe in the Bogomol'nyi-Prasad-Sommerfield limit.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 11, pp. 89–93, November, 1982.     

On the Goldstonic gravitation theory

The physical specificity of gravity as a Goldstone-type field responsible for spontaneous breaking of space-time symmetries is investigated and extended up to supergravity. Problems of the Higgs gravitation vacuum and its matter sources are discussed. A particular “dislocation” structure of a space-time due to Poincaré translation gauge fields and the corresponding modification of Newton’s gravitational potential are predicted.     

On the theory of space-time polarization holography

Polarization holographic recording and the reconstruction of the field of a nonstationary object wave are considered theoretically. Expressions for the nondiffracted beam, as well as the virtual and real images, formed by a space-time polarization hologram are analyzed. It is shown that, under certain conditions imposed on the isotropic, anisotropic, and gyrotropic responses of a polarization-sensitive medium, one can adequately reconstruct the space structure, time waveform, and polarization characteristics of the field of a nonstationary object in the virtual image.     

Gravitating Julia-Zee dyon and the cosmological term

The relation between the spherically symmetric Julia-Zee dyon of the coupled Yang-Mills-Higgs system and the cosmological term is studied in curved space-time. It is pointed out that the cosmological term comes out of the Higgs field.     

Space-time geometry and symmetry breaking

We look for solutions of the Einstein-Yang-Mills equations in a 4 + D dimensional space-time. We find solutions where the first 4 dimensions are a flat Minkowskian space-time, while the D others are a compact, space-like manifold of small size. Such solutions can be obtained for an arbitrary compact gauge group K and are invariant under a sub-group G of K related to the space-time geometry. This shows that 4 + D dimensional gravity can give a mechanism for the super-strong symmetry breaking needed in grand unified field theories without introducing Higgs scalars.
