Heinrich Wahl

from Wikipedia, the free encyclopedia

Heinrich Wahl (born February 7, 1938 in Würzburg ) is a German experimental particle physicist .

life and work

Wahl studied physics at the TH Munich , the ETH Zurich and the University of Hamburg , where he received his doctorate in 1967 on nuclear magnetic resonance fluorescence . As a post-doc he was at DESY , where he researched the photoproduction of mesons at high energies (F35 collaboration). From 1969 he was a member of CERN , where he retired in 2003. He is a professor at the University of Ferrara .

He was involved in the CDHS experiment (CERN-Dortmund-Heidelberg- Saclay ) started in 1976 under Jack Steinberger to investigate high-energy neutrino scattering .

Wahl was already concerned with the decay of the kaons in the early 1970s . In the 1980s, he was spokesman for the NA31 experiment at SPS - accelerator at CERN, in 1988, the direct detection of in which CP violation in K mesons system succeeded. ( James Cronin and Val Fitch had already succeeded in providing indirect evidence in 1964 from the mixed states of the neutral kaon system, for which they received the Nobel Prize in Physics in 1980. ) In the 1990s, Wahl was involved in the follow-up experiment NA48 , which they had before most accurate determination of the parameters of the CP violation provided. This also happened at the same time in the KTEV experiment at the Tevatron ( Bruce Winstein et al.).

honors and awards

In 1970 he received the Gustav Hertz Prize (at that time still the DPG Physics Prize ).

In 2005, together with the NA31 collaboration, he received the High Energy Physics Prize of the European Physical Society for the discovery of direct CP violation.

In 2007 he received the Panofsky Prize with Bruce Winstein and Italo Mannelli for his leading role in a series of experiments that resulted in a variety of precision measurements of properties of the system of neutral K mesons, in particular for the discovery of direct CP violation .
