Slow Neutrinos?

The "faster-than-light neutrino" result was probably an error. OPERA admits that faster than light Neutrino measurement may have been an error.

The OPERA’s official statement reads in full:

“The OPERA Collaboration, by continuing its campaign of verifications on the neutrino velocity measurement, has identified two issues that could significantly affect the reported result. The first one is linked to the oscillator used to produce the events time-stamps in between the GPS synchronizations. The second point is related to the connection of the optical fiber bringing the external GPS signal to the OPERA master clock.
These two issues can modify the neutrino time of flight in opposite directions. While continuing our investigations, in order to unambiguously quantify the effect on the observed result, the Collaboration is looking forward to performing a new measurement of the neutrino velocity as soon as a new bunched beam will be available in 2012. An extensive report on the above mentioned verifications and results will be shortly made available to the scientific committees and agencies.”

INFN goes overseas

Between 5 and 6th February, INFN met the delegations from the American Department of Energy (DOE) and the National Science Foundation (NSF) in order to establish a new scientific cooperation among Italy and USA. We talked about this meeting with Antonio Masiero, the INFN Deputy Director. “The collaboration between these two countries is excellent,” says Masiero, “and at the moment it involves four research projects, which are the topics we have discussed two weeks ago in Washington.”
