It is a remarkable confirmation of a stunning result; but most physicists remain skeptical. That seems the most probable outcome of a release of new data expected on 17 November from researchers with the Italian OPERA collaboration, who say they have confirmed their controversial finding that flighty subatomic neutrinos can travel faster than light.
“It’s slightly better than the previous result,” says OPERA’s physics coordinator Dario Autiero of the Institut de Physique Nucleaire de Lyon in France (pictured). He adds that most of the members of the collaboration who declined to sign the original paper because they wanted more time to check the result have now come on board. One of these is Caren Hagner of the University of Hamburg in Germany. She says not only has the experiment’s precision been improved, the statistical analysis is more robust and has been replicated by different groups within OPERA not just the original team. “We gained much more confidence,” Hagner says.
