Im Rahmen eines Sonderseminars am Fermilab (Fermi National Accelerator Laboratory) in der Nähe von Chicago wurden am 11. April 2007 die mit Spannung erwarteten ersten Resultate des Beschleuniger-Neutrinoexperiments MiniBooNE der internationalen Fachwelt vorgestellt. Von besonderem Interesse waren die Ergebnisse des US-Experiments für die Neutrinoforscher am Institut für Kernphysik des Forschungszentrums Karlsruhe, die von 1997 bis 2001 mit dem KARMEN-Experiment am ISIS-Beschleuniger in England, ebenso wie jetzt die amerikanischen Forscher, auf der Suche nach Neutrino-Oszillationen waren. Während in einem Vorläufer-Experiment von MiniBooNE, dem LSND-Experiment am Los Alamos Beschleuniger, ein Signal für Neutrino-Oszillationen gefunden wurde, fanden die Karlsruher Neutrinophysiker am ISIS-Beschleuniger keinen Ebrmptm rtj tpcbyagef Nslppdhy.
