چکیده
A non-linear gravitational model with a multidimensional geometry and quadratic scalar curvature is considered. For certain parameter ranges, the extra dimensions are stabilized if the internal spaces have negative constant curvature. As a consequence, the 4–dimensional effective cosmological constant as well as the bulk cosmological constant become negative. The homogeneous and isotropic external space is asymptotically AdS4. The connection between the D–dimensional and the 4– dimensional fundamental mass scales sets an additional restriction on the parameters of the considered non-linear models.

The main tools in cosmology for comparing theoretical models with the observations of the galaxy distribution are statistical. We will review the applications of spatial statistics to the description of the large-scale structure of the universe. Special topics discussed in this talk will be: description of the galaxy samples, selection effects and biases, correlation functions, Fourier analysis...

Abstract. We review certain results for amplitudes of spectral flowed operators in string theory on AdS3. We present the modified Knizhnik-Zamolodchikov and null vector equations to be satisfied by correlators including w = 1 operators. We then discuss the three point function of two w = 1 and one w = 0 operators in the x-basis, and perform a consistency check on the definition of the w = 1 ope...

Inclusive transverse momentum spectra of single electrons from Au+Au collisions have been measured at √ s N N = 130 GeV and 200 GeV at midrapidity by the PHENIX experiment at RHIC. After subtraction of background from photon conversions and light hadron decays, the spectra appear consistent with semileptonic decays of charmed particles.

The Bianchi type I cosmological model is brought into a form where the evolution of observables is governed by the unconstrained Hamiltonian that coincides with the Hamiltonian describing the relative motion of particles in the integrable 3-body hyperbolic Euler-Calogero-Sutherland system.
