writes: The CERN team who announced neutrinos may travel faster than light has carried out an improved version of their experiment — and found the same result.
Acknowledged critics of the first report had said that the long bunches of neutrinos used could introduce an error into the test.
The new work, posted to http://arxiv.org/pdf/1109.4897v2, used much shorter bunches.
It has been submitted to the Journal of High Energy Physics, but has not yet been reviewed by the scientific community.
