OPERA experiment invites scrutiny of unexpected results

Oujda Portail: A view of the OPERA detector in Gran Sasso, Italy. Neutrino beams from CERN in Switzerland are sent over 700km through the Earth’s crust to the laboratory in Italy.

The OPERA experiment, which observes a neutrino beam from CERN 730 km away at Italy’s INFN Gran Sasso Laboratory, will present new results in a seminar at CERN today.

The OPERA result is based on the observation of over 15000 neutrino events measured at Gran Sasso, and appears to indicate that the neutrinos travel at a velocity 20 parts per million above the speed of light, nature’s cosmic speed limit. Given the potential far-reaching consequences of such a result, independent measurements are needed before the effect can either be refuted or firmly established. This is why the OPERA collaboration has decided to open the result to broader scrutiny.
