Running couplings and operator mixing in the gravitational corrections to coupling constants
Running couplings operator mixing gravitational corrections
2010/12/21
The use of a running coupling constant in renormalizable theories is well known, but the imple-
mentation of this idea for effective field theories with a dimensional coupling constant is in general ...
Fine structure of the Poynting-Robertson effect for a luminous spinning relativistic star
Fine structure Poynting-Robertson effect luminous spinning relativistic star
2010/12/21
As a sequel to our recent works challenging toward the systematic inclusion of the effect of
radiation on the trajectory of a test particle orbiting around a luminous spinning relativistic star event...
Finite size effects on the Poynting-Robertson effect: a fully general relativistic treatment
Poynting-Robertson general relativistic treatment
2010/12/21
Even since the first discovery of Poynting and Robertson, the radiation source has been treated
as merely a point. Even in a very few studies where the size of the source has been taken
into account...
A comparison of Hořava-Lifshitz gravity and Einstein gravity through thin-shell wormhole construction
comparison of Hoř ava-Lifshitz gravity Einstein gravity thin-shell wormhole construction
2010/12/20
In this paper we have constructed a new class of thin-shell wormholes from black holes in Hoˇrava-Lifshitz gravity. Particular emphasis is placed on those aspects that allow a comparison of Hoˇrava-Li...
This introduction is intended for students taking a first course in Nuclear and Particle Physics. Electron‐positron annihilation‐in‐flight is discussed as a topical example of an exact relativistic an...
Statistical and dynamical fluctuations in the ratios of higher cumulants in relativistic heavy ion collisions
Statistical and dynamical fluctuations ratios of higher cumulants relativistic heavy ion collisions
2011/1/6
With the help of transport and statistical models, we find that the ratios of higher net-proton
cumulants measured at RHIC are dominated by the statistical fluctuations. Future measurements
should f...
Stability of general-relativistic accretion disks
Stability general-relativistic accretion disks
2010/12/21
Self-gravitating relativistic disks around black holes can form as transient structures in a number of astrophysical scenarios such as binary neutron star and black hole-neutron star coalescences, as ...
Galilean symmetry in the effective theory of inflation: new shapes of non-Gaussianity
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
cosmological solution Scalar-Tensor Gravity theory compatible $\Lambda$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.
Relativistic point-form approach to hadron properties
Relativistic point-form hadron properties
2011/1/7
We present a review of the description of hadron properties along an invariantmass operator in the point form of Poincaré-invariant relativistic dynamics. The quark-quark interaction is furnished by a...
A brief review of relativistic effects in few-body systems, of theoretical approaches,recent developments and applications is given. Manifestations of relativistic effects in the binding energies, in ...
Strengthening constraints on Yukawa-type corrections to Newtonian gravity from measuring the Casimir force between a cylinder and a plate
Newtonian gravity Casimir force cylinder plate
2010/12/20
We discuss possibility to obtain stronger constraints on non-Newtonian gravity from measuring
the gradient of the Casimir force between a cylinder and a plate. Exact analytical expression
for the Yu...

2011/1/10
A novel lattice approach is presented for studying systems comprising a large number of interacting nonrelativistic fermions.

Relativistic quantum mechanics Few-body systems Electromagnetic structure
2011/1/6
We discuss a Poincar´e invariant coupled-channel formalism which is based on the point-form of relativistic quantum mechanics.
More on the dilatonic Einstein-Gauss-Bonnet gravity
dilatonic Einstein-Gauss-Bonnet gravity
2010/12/21
Einstein-Gauss-Bonnet gravity coupled to a dynamical dilaton is examined from the viewpoint
of Einstein’s equivalence principle. We point out that the usual frame change that applies to
the action w...
