ERC Advanced Grant for Eberhard Widmann

Eberhard Widmann, Director of the Stefan Meyer Institute for subatomic Physics recieved a Advanced Investigator Grant of the ERC (European Research Council).
His project "Hyperfine Structure of Antihydrogen HBAR-HFS" will be aided with about 2,6 million Euro over a period of five years. The ERC Advanced Grant is awarded for pioneering in fundamental research and is deemed to be the highest honor for european top scientists.



Das Stefan-Meyer-Institut für Subatomare Physik widmet sich dem Studium fundamentaler Symmetrien und Wechselwirkungen, um folgende Fragen zu beantworten:

  • Was sind die Eigenschaften der in der Natur vorkommenden Kräfte?
  • Was ist der Ursprung der Masse des sichtbaren Universums?
  • Warum besteht das aus dem Big Bang hervorgegangene Universum nur aus Materie und nicht auch aus Antimaterie?

Als Methode benutzen wir Präzisionsspektroskopie von exotischen Atomen (Atome, die anstelle eines Elektrons ein anderes Elementarteilchen wie z.B. ein Pion, ein Kaon oder ein Antiproton enthalten) und exotischen gebundenen Zuständen zwischen Mesonen und Kernen. Das SMI ist an mehreren internationalen Kollaborationen beteiligt, die ein breites Forschungsprogramm an führenden internationalen Beschleunigerzentren (CERN/Genf CH, LNF-INFN/Frascati IT, J-PARC/Tokai JP, GSI/Darmstadt DE und in der Zukunft FAIR/Darmstadt DE) durchführen.

The Stefan Meyer Institute (SMI) is devoted to basic research in the field of subatomic physics. Our research focuses on the study of fundamental symmetries and interactions, addressing the following questions:

  • What are the properties of the forces that exist in nature?
  • What is the origin of the masses of the visible universe?
  • Why do the remains of the Big Bang consist only of matter and not also of antimatter?

We specialise in precision spectroscopy of exotic atoms (Atoms that contain another particle - e.g. an antiproton, kaon, muon or pion- in their shell instead of an electron) and exotic meson-nucleus bound states as an integral part of international collaborations at large-scale research facilities including CERN (Geneva, Switzerland), LNF-INFN (Frascati, Italy), J-PARC (Tokai, Japan), GSI (Darmstadt, Germany), and, in the future, FAIR (Darmstadt, Germany).
