Probing for dynamics of dark energy and curvature of universe with latest cosmological observations
Gong-Bo Zhao, Jun-Qing Xia, Hong Li +4
We use the newly released 182 Type Ia supernova data combined with the third-year Wilkinson Microwave Anisotropic Probe data (WMAP3) and large scale structure (LSS) information inc…
Vanishing of Beta Function of Non Commutative Theory to all orders
M. Disertori, R. Gurau, J. Magnen +1
The simplest non commutative renormalizable field theory, the model on four dimensional Moyal space with harmonic potential is asymptotically safe up to three loops, as shown…
Parafermions, Brane Distributions and FRW Hierarchies
P. M. Petropoulos
I review a class of exact string backgrounds, which appear in hierarchies, where the boundary of the target space of an exact sigma model is itself the target space of another exac…
Deeply Virtual Compton Scattering on a Photon and Generalized Parton Distributions in the Photon
S. Friot, B. Pire, L. Szymanowski
We consider deeply virtual Compton scattering on a photon target, in the generalized Bjorken limit, at the Born order and in the leading logarithmic approximation. We interpret the…
Testing for monotonicity in the Hubble diagram
Nicolai Meinshausen, John Rice, Thomas Schücker
General relativistic kinematics and the cosmological principle alone imply a monotonicity constraint in the Hubble diagram, which we confront to present-day supernova data. We use…
Quantum field theory on projective modules
V. Gayral, J. -H. Jureit, T. Krajewski +1
We propose a general formulation of perturbative quantum field theory on (finitely generated) projective modules over noncommutative algebras. This is the analogue of scalar field…
