The Ghost of Sagittarius and Lumps in the Halo of the Milky Way
Heidi Jo Newberg, Brian Yanny, Constance M. Rockosi +16
We identify new structures in the halo of the Milky Way Galaxy from positions, colors and magnitudes of five million stars detected in the Sloan Digital Sky Survey. Most of these s…
Functional Callan-Symanzik equation for QED
J. Alexandre, J. Polonyi, K. Sailer
An exact evolution equation, the functional generalization of the Callan-Symanzik method, is given for the effective action of QED where the electron mass is used to turn the quant…
Bias in Matter Power Spectra ?
M. Douspis, A. Blanchard, J. Silk
We review the constraints given by the linear matter power spectra data on cosmological and bias parameters, comparing the data from the PSCz survey (Hamilton et al., 2000) and fro…
Lectures on the functional renormalization group method
Janos Polonyi
These introductory notes are about functional renormalization group equations and some of their applications. It is emphasised that the applicability of this method extends well be…
Effective action and density functional theory
J. Polonyi, K. Sailer
The effective action for the charge density and the photon field is proposed as a generalization of the density functional. A simple definition is given for the density functional,…
Axial structure of the nucleon
Véronique Bernard, Latifa Elouadrhiri, Ulf-G. Meißner
We review the current status of experimental and theoretical understanding of the axial nucleon structure at low and moderate energies. Topics considered include (quasi)elastic (an…
Rapidity dependence of antiproton to proton ratios in Au+Au collisions at sqrt{s_{NN}}=130 GeV
BRAHMS Collaboration, I. G. Bearden
Measurements, with the BRAHMS detector, of the antiproton to proton ratio at central and forward rapidities are presented for Au+Au reactions at sqrt{s_{NN}}=130 GeV, and for three…
Numerical characterization of the Kähler cone of a compact Kähler manifold
Jean-Pierre Demailly, Mihai Paun
The goal of this work is give a precise numerical description of the Kähler cone of a compact Kähler manifold. Our main result states that the Kähler cone depends only on the inter…
The branching nerve of HDA and the Kan condition
Philippe Gaucher
One can associate to any strict globular -category three augmented simplicial nerves called the globular nerve, the branching and the merging semi-cubical nerves. If this strict…
Shell Model Description of Isotope Shifts in Calcium
E. Caurier, K. Langanke, G. Martinez-Pinedo +2
Isotope shifts in the nuclear charge radius of even and odd calcium isotopes are calculated within the nuclear shell model. The model space includes all configurations of nucleons…
Aspects of near threshold neutral pion photoproduction off protons
Véronique Bernard, Norbert Kaiser, Ulf-G. Meißner
We investigate near threshold neutral pion photoproduction off protons to fourth order in heavy baryon chiral perturbation theory in the light of the new data from MAMI. We show th…
