New results of the OPERA long-baseline experiment in the CNGS neutrino beam

In May 2012 the CERN-CNGS neutrino beam operated in a dedicated short-bunched mode for two weeks in order to provide the opportunity to measure muon neutrino speed on an event-byevent basis. This new measurement campaign was the follow-up of a previous anomalous result reported by the OPERA Collaboration which was later revised and corrected by the Collaboration. The new analysis profited from the precision geodesy measurements of the neutrino baseline and of the CNGS/LNGS clock synchronization performed in the previous analysis. Different OPERA sub-detectors and timing systems were used and results were given separately for nm and ¯ nm exploiting the information provided by the muon spectrometers.
