An experiment to repeat a test of neutrinos has found that they do not travel faster than light.
Last September, a preliminary but electrifying result suggested these ghostly subatomic particles might travel faster than light. Now, in what may well be the final nail in the coffin for the claim that neutrinos travel faster than light, scientists from the ICARUS Group, which is also in Gran Sasso, have announced that they’ve measured neutrinos travelling from CERN, and determined that those neutrinos were not travelling faster than light. The ICARUS Detector examined data from neutrinos sent from CERN to Gran Sasso. These neutrinos were from the same pulse that were sent to OPERA, so if the neutrinos were travelling faster than light, the ICARUS detector should have measured that, as well. However, when ICARUS reviewed their data, they found that the result is compatible with the simultaneous arrival of all the 7 events with the speed of light and not compatible with respect to the result reported by OPERA. In order to finally verify whether neturinos from CERN are travelling faster than light, CERN will be working with the Gran Sasso laboratories for a final measurement this May. According to CERN Research Director Sergio Bertolucci the evidence is beginning to point towards the OPERA result being an artefact of the measuremen but it’s important to be rigorous, and the Gran Sasso experiments, BOREXINO, ICARUS, LVD and OPERA will be making new measurements with pulsed beams from CERN in May to give us the final verdict.
