2005 Prizes of the High Energy and Particle Physics Division of the European Physical Society

The 2005 European Physics Society High Energy and Particle Physics Prize is awarded jointly to

Heinrich Wahl, for his outstanding leadership of challenging experiments on CP Violation, and to
the NA 31 Collaboration, which showed for the first time Direct CP Violation in the decays of neutral K mesons. "

The 2005 EPS-HEPP Young Physicist Prize is awarded to

Mathieu de Naurois, for his new ideas and decisive contributions in the CELESTE and HESS experiments. His new original method to analyse Cerenkov images of atmospheric showers enabled many new results in HESS and the detection of new sources near the galactic center. "

The 2005 EPS-HEPP Gribov Medal is awarded to

Matias Zaldarriaga, for his important theoretical contributions to Cosmology, with impact also on the theories of fundamental interactions. Among others for:
1. developing an efficient method for calculating the observed CMB fluctuations in a given cosmological model. This has greatly facilitated imposing constraints on cosmological models and is widely used.
2. Realizing the importance of polarization in the CMB and the possibility to measure it.
3. Pointing out the importance of the effect of gravitational lensing by local matter on the CMB background."

The 2005 Outreach Prize is awarded jointly to

Dave Barney, for promoting the fascination of particle physics to the public, in parallel to his research work in the CMS collaboration at CERN. His impressive and successful efforts are concentrated around the CMS experiment, but also reaching far beyond his own experiment.
Peter Kalmus, for his long-standing and major personal involvement in particle physics outreach. In the last years, he has given talks for schools and the public to a total audience of some 24,000 in countries from the UK, Ireland and France to South Africa, Singapore and India. "
