Conformal General Relativity
The inflation-free solution of problems of the modern cosmology (horizon,
cosmic initial data, Planck era, arrow of time, singularity,homogeneity, and so
on) is considered in the conformal-invariant unified theory given in the space
with geometry of similarity where we can measure only the conformal-invariant
ratio of all quantities. Conformal General Relativity is defined as the
-Standard Model where the dimensional parameter
in the Higgs potential is replaced by a dilaton scalar field described by the
negative Penrose-Chernikov-Tagirov action. Spontaneous SU(2) symmetry breaking
is made on the level of the conformal-invariant angle of the dilaton-Higgs
mixing, and it allows us to keep the structure of Einstein's theory with the
equivalence principle. We show that the lowest order of the linearized
equations of motion solves the problems mentioned above and describes the Cold
Universe Scenario with the constant temperature T and z-history of all masses
with respect to an observable conformal time. A new fact is the intensive
cosmic creation of -vector bosons due to their mass singularity. In the
rigid state, this effect is determined by the integral of motion that coincides with the CMB temperature and has the
meaning of the primordial Hubble parameter. The created bosons are enough to
consider their decay as an origin of the CMB radiation and all observational
matter with the observational element abundances and the baryon asymmetry.
Recent Supernova data on the relation between the luminosity distance and
redshift (including the point ) do not contradict the dominance of the
rigid state of the dark matter in the Conformal Cosmology.Comment: 8 pages, Latex file, 2 figures, Invited talk given at the V

Cosmic Evolution as Inertial Motion in the Field Space of GR
The identification of a cosmic scale function with the volume integral of a
spacelike hypersurface defines the cosmic evolution in General Relativity as a
collective motion along a geodesic in the field space of the metric components,
considered as the coset of the affine group over the Lorentz one.
The Friedmann equations are derived out of the homogeneous approximation by
the Gibbs averaging exact equations over the relative constant spatial volume.
A direct correspondence between the collective cosmic motion and Special
Relativity is established, to solve the problem of time and energy by analogy
with the solution of this problem for a relativistic particle by Poincare and
Einstein.
A geometrical time interval is introduced into quantum theory of the
relativistic collective motion by the canonical Levi-Civita -- type
transformation in agreement with the correspondence principle with quantum
field theory. In this context the problem of quantum cosmological creation of
visible matter is formulated.
We show that latest observational data can testify to the relative
measurement standard, and the cosmic evolution as an inertial motion along
geodesic in the field space.Comment: RevTex file, 23 pages, 1 figure. Talk submitted to the 9th Course on

Cosmological Particle Creation and Baryon Number Violation in a Conformal Unified Theory
We consider a conformal unified theory as the basis of conformal-invariant
cosmological model where the permanent rigid state of the universe is
compatible with the primordial element abundance and supernova data. We show
that the cosmological creation of vector Z and W bosons, in this case, is
sufficient to explain the CMB temperature (2.7 K). The primordial bosons
violate the baryon number in the standard model as a result of anomalous
nonconservation of left-handed currents and a nonzero squeezed vacuum
expectation value of the topological Chern-Simons functional.Comment: LaTex file, 12 pages, 1 figur
Cosmological Creation of Vector Bosons and Fermions
The cosmological creation of primordial vector bosons and fermions is
described in the Standard Model of strong and electro-weak interactions given
in a space-time with the relative standard of measurement of geometric
intervals. Using the reparametrization - invariant perturbation theory and the
holomorphic representation of quantized fields we derive equations for the
Bogoliubov coefficients and distribution functions of created particles. The
main result is the intensive cosmological creation of longitudinal Z and W
bosons (due to their mass singularity) by the universe in the rigid state. We
introduce the hypothesis that the decay of the primordially created vector
bosons is the origin of the Cosmic Microwave Background radiation.Comment: 20 pages, 1 figure, discussion extended, typos correcte
Cosmological Consequences of Conformal General Relativity
We consider cosmological consequences of a conformal-invariant unified theory
which is dynamically equivalent to general relativity and is given in a space
with the geometry of similarity. We show that the conformal-invariant theory
offers new explanations for to such problems as the arrow of time, initial
cosmic data, dark matter and accelerating evolution of the universe in the dust
stage.Comment: 12 pages, talk presented at "Hot Points in Astrophysics", JINR Dubna,

Origin of Matter from Vacuum in Conformal Cosmology
We introduce the hypothesis that the matter content of the universe can be a
product of the decay of primordial vector bosons.
The effect of the intensive cosmological creation of these primordial vector
bosons from the vacuum is studied in the framework of General
Relativity and the Standard Model where the relative standard of measurement
identifying conformal quantities with the measurable ones is accepted.
The relative standard leads to the conformal cosmology with the z-history of
masses with the constant temperature, instead of the conventional z-history of
the temperature with constant masses in inflationary cosmology.
In conformal cosmology both the latest supernova data and primordial
nucleosynthesis are compatible with a stiff equation of state associated with
one of the possible states of the infrared gravitation field.
The distribution function of the created bosons in the lowest order of
perturbation theory exposes a cosmological singularity as a consequence of the
theorem about the absence of the massless limit of massive vector fields in
quantum theory. This singularity can be removed by taking into account the
collision processes leading to a thermalization of the created particles. The
cosmic microwave background (CMB) temperature T=(M_W^2H_0)^{1/3} ~ 2.7 K occurs
as an integral of motion for the universe in the stiff state. We show that this
temperature can be attained by the CMB radiation being the final product of the
decay of primordial bosons.
The effect of anomalous nonconservation of baryon number due to the
polarization of the Dirac sea vacuum by these primordial bosons is considered.Comment: Latex file, 19 pages, 2 figures, Preprint JINR E2-2002-14
Relative Standard of Measurement and Supernova Data
We show that in the units of the relative Paris meter both the latest data on the Supernova luminosity-distance -- redshift relation and primordial nucleosynthesis are described by the dynamics of a homogeneous, massless scalar field (Scalar Quintessence) in a nonexpanding universe
Astrophysics in relative units as the theory of a conformal brane
The latest astrophysical data on the Supernova luminosity--distance --
redshift relations, primordial nucleosynthesis, value of Cosmic Microwave
Background--temperature, and baryon asymmetry are considered as an evidence of
relative measurement standard, field nature of time, and conformal symmetry of
the physical world. We show how these principles of description of the universe
help modern quantum field theory to explain the creation of the universe, time,
and matter from the physical vacuum as a state with the lowest energy.Comment: 25 pages, 6 figures, LaTe
