Wasn't this formally disproven, that particles (neutrinos) can go faster than light? A technical issue I think was at play, or some miscalculations that did not take the effects of relativity into account properly.
Indeed, all the experiments located under Gran Sasso are reporting measured speeds compatible with light speed (in the vacuum). Here's the CERN press release:

There are also named two possible causes of the original, unexpected result.
