Neutrino OPERA experiments

After 3 years of data taking in the CNGS neutrino beam from CERN with the OPERA detector at LNGS, and several months of analysis and checks, a really unexpected result has come out last week: the time of flight of CNGS neutrinos detected by OPERA appears to be shorter by 20 parts per million as compared to that of light. The researchers, after a careful scrutiny of statistical and systematical errors have decided to publicize this astonishing anomaly with a series of seminars and with a paper recently appeared on the archives.
