Einstein–Yang–Mills-Aether Theory with Nonlinear Axion Field: Decay of Color Aether and the Axionic Dark Matter Production
Round 1
Reviewer 1 Report
The paper is well written but the theory presented here is very sophisticate and speciallized. The manuscript is correctly presentated and can be accepted for publication in Symmetry.

Reviewer 3 Report
*************************************************************************
Referee's report on the article "Einstein-Yangs-Mill-Aether Theory with
Nonlinear Axion Field: Decay of Color Aether and teh Axionic Dark Matter
Production, by Blakin & Kiselev, submitted for consideration to the Journal
Symmetry.
*************************************************************************
The article deals with a new axiomatic nonlinear model of the SU(N)
symmetric theory using interactions between gravitational, gauge, vector
and pseudo-scalar fields. The SU(N) symmetric multiplet of the vector
fields is associated with a symmetric dynamic ether or "colour aether"
which in the early stages of the Universe produces aether and axionic
dark matter. The source comes from a SU(N) symmetric Yangs-Mills field
and is associated to the colour aether. This field transfers energy from
the decaying field to the axion field. The non-linearity added to the
model is very simple and resembles the non-linear pendulum. The advantage
of this non-linearity addition is that the axion field can grow to an
arbitrary large value, which is in principle important for explaining
the great abundance of dark matter in the form of axions in the universe.
The article is very good, well written and shows that the addition of a
non-linearity is most probably the way to interpret the production of a
huge amount of axionic dark matter in the universe. I recommend the
article for publication in Symmetry after the following minor comment is
addressed by the authors:
(*) It is quite interesting to see that the axion field can grow
to very large values with this model. However, from astronomical and
cosmological observations we know that there is ~90% more non-baryonic dark
matter than baryonic matter. I think that the authors should try to
explain the possible causes of why the presented model may produce such a
fine-tuned value of axionic dark matter.
