Possible Dark Matter Signals from Antiprotons, Positrons, X-rays and Gamma-rays

A number of signals involving charged cosmic rays and high-energy photons have been interpreted as being due to annihilating dark matter. This article provides an overview of the experimental evidence and discusses in particular detections of antiprotons and positrons in the cosmic radiation, the diffuse gamma-ray emission between 10 MeV and 100 GeV from the Milky Way, and the 511 keV annihilation radiation and the flux of very high-energy photons (>100 GeV) from the Galactic Centre.

HERA-B Framework for Online Calibration and Alignment

This paper describes the architecture and implementation of the HERA-B framework for online calibration and alignment. At HERA-B the performance of all trigger levels, including the online reconstruction, strongly depends on using the appropriate calibration and alignment constants, which might change during data taking. A system to monitor, recompute and distribute those constants to online processes has been integrated in the data acquisition and trigger systems.

Status of the H.E.S.S. Experiment

The H.E.S.S. experiment (High Energy Stereoscopic System) is a new generation atmospheric Cherenkov detector measuring high-energy (>100 GeV) gamma radiation from the Universe. This paper briefly explains the imaging Cherenkov technique and describes the H.E.S.S. project and its current status.
