CERN Press Release dt. 23 September 2011
The OPERA experiments have a result to report. The result is based on the observation of over 15000 neutrino events measured at Gran Sasso (receiving station of neutrinos), and appears to indicate that the neutrinos travel at a velocity 20 parts per million above the speed of light, nature’s cosmic speed limit. Scientists announced that given the potential far-reaching consequences of such a result, which is contrary to existing theory, independent measurements are needed before the observed effect can either be refuted or firmly established.
The paper can be downloaded: http://static.arxiv.org/pdf/1109.4897.pdf
The seminar given by the scientists on 23.9.2011 can be accessed through video streaming at:
