General formulation of general-relativistic higher-order gauge-invariant perturbation theory
General formulation general-relativistic higher-order gauge-invariant perturbation theory
2010/12/20
Gauge-invariant treatments of general-relativistic higher-order perturbations on generic back-
ground spacetime is proposed. After reviewing the general framework of the second-order gauge-
invarian...
A thermal field theory derivation of the source term induced by a fast parton from the quark energy-momentum tensor
thermal field theory derivation of the source term fast parton quark energy-momentum tensor
2011/1/10
I derive the distribution of energy and momentum transmitted from a fast parton to a medium of
thermalized quarks, or the source term, in perturbative thermal field theory directly from the quark ene...

2010/12/21
We construct finite mass, asymptotically flat black hole solutions in d = 5 Einstein–Yang-Mills–Chern-Simons theory. Our results indicate the existence of a second order phase transition between Reiss...
Nonrelativistic general covariant theory of gravity with a running constant $\lambda$
Nonrelativistic general covariant theory of gravity constant $\lambda$
2010/12/21
In this paper, we investigate three important issues: ghost, stability and strong coupling, in
the Horava-Melby-Thompson (HMT) setup of the Horava-Lifshitz (HL) theory with 6= 1. We
first develop ...
Two problems of theory of gravitation
Foundation of gravitation theory Equations of gravitation
2010/12/20
This paper aims to discuss two issues that can have a significant impact on the foundations of the theory of gravitation:1. The existence of relativity of space-time geometry with respect to the prope...
Complementarity of Kinematics and Geometry in General Relativity Theory
Complementarity of Kinematics Geometry General Relativity Theory
2010/12/20
Relations between kinematics, geometry and law of reference frame motion are considered. We show, that kinematical tensors define geometry up to a space functiona arbitrariness when integrability cond...
The sphaleron rate is defined as the diffusion constant for topological number NCS ≡ R g2F ˜ F 322 .It establishes the rate of equilibration of axial light quark number in QCD and is of interest...

Galilean symmetry effective theory of inflation shapes of non-Gaussianity
2010/12/21
We study the consequences of imposing an approximate Galilean symmetry on the Effective Theory
of Inflation, the theory of small perturbations around the inflationary background. This approach allows...
An exact cosmological solution of a Scalar-Tensor Gravity theory compatible with the $\Lambda$CDM model

2010/12/21
We consider the massive Scalar-Tensor theory in the Jordan frame F() = K22,Z() = 1, and U() = (1/2)m22, F() corresponds to a constant Brans-Dicke parameter !BD = 1/4K2.

2010/12/21
We discuss the Bianchi type-V II0 cosmology with Dirac field in Einstein-Cartan the-ory. We obtain the equations of Dirac field and gravitational field in Einstein-Cartan theory. We find a Bianchi typ...

2010/11/4
A simple relativistic quantum hidden-variable theory of particle trajectories, similar to the Bohm theory but without nonlocal forces between the particles, is proposed. To provide compatibility with...

Bohr-Somerfeld-Hansson Theory Newtonian Gravity
2010/10/26
In this work we consider some consequences of the Bohr-Sommerfeld-Hansson (Old or
quasi-classical) quantum theory of the Newtonian gravity, i.e. of the ”gravitational atom”.
We prove that in this ca...
