Asymptotic Freedom from Induced Gravity Cosmology

چکیده
We give conditions to obtain cosmological asymptotic freedom in scalar–tensor theories of gravity. We show that this feature can be achieved in FRW flat spacetimes since we obtain singularity free solutions where the effective gravitational constant Geff → 0 for t → −∞ and, for some of them, Geff → GN for t → ∞, where GN is the Newton constant.

Asymptotic Freedom Cosmology
For a general class of scalar–tensor gravity theories, we discuss how to recover asymptotic freedom regimes when cosmic time t → ±∞. Such a feature means that the effective gravitational coupling Geff → 0, while cosmological solutions can asymptotically assume de Sitter or power–law behaviours. In our opinion, through this mechanism, it is possible to cure some shortcomings in inflationary and ...
متن کاملString Dilaton Fluid Cosmology
We investigate (n+ 1)-dimensional string-dilaton cosmology with effective dilaton potential in presence of perfect-fluid matter. We get exact solutions parametrized by the constant γ of the state equation p = (γ−1)ρ, the spatial dimension number n, the bulk of matter, and the spatial curvature constant k. Several interesting cosmological behaviours are selected. Finally we discuss the recoverin...
متن کاملAsymptotic freedom of Yang-Mills theory with gravity
We study the behaviour of Yang-Mills theory under the inclusion of gravity. In the weakgravity limit, the running gauge coupling receives no contribution from the gravitational sector, if all symmetries are preserved. This holds true with and without cosmological constant. We also show that asymptotic freedom persists in general field-theory-based gravity scenarios including gravitational shiel...
متن کاملAsymptotic Freedom 1. Understanding Asymptotic Freedom in Qcd
I discuss how the basic phenomenon of asymptotic freedom in QCD can be understood in elementary physical terms. Similarly, I discuss how the long-predicted phenomenon of “gluonization of the proton” – recently spectacularly confirmed at HERA – is a rather direct manifestation of the physics of asymptotic freedom. I review the broader significance of asymptotic freedom in QCD in fundamental phys...
متن کاملDilatonic gravity near two dimensions and asymptotic freedom of the gravitational coupling constant
Two models of dilatonic gravity are investigated: (i) dilaton-Yang-Mills gravity and (ii) higher-derivative dilatonic gravity. Both are renormalizable in 2 + ǫ dimensions and have a smooth limit for ǫ → 0. The corresponding one-loop effective actions and beta-functions are found. Both theories are shown to possess a non-trivial ultraviolet fixed point —for all dilatonic couplings— in which the ...
