Faster-than-light neutrino measurement withstands new test

The OPERA experiment’s surprising superluminal neutrino result is holding fast after a new measurement designed to eliminate a possible source of systematic error from their previous tests.

OPERA scientists reported the new results in a press release and a paper released on the arXiv today.

“The positive outcome of the test makes us more confident in the result,” said Fernando Ferroni, president of the Italian Institute for Nuclear Physics. But “a final word can only be said by analogous measurements performed elsewhere in the world.”

Accordingly, OPERA and other experiments, including Fermilab’s MINOS and KEK laboratory’s T2K, will continue collecting data in the coming year.
