Slow Neutrinos?

Read time: 1 min

The "faster-than-light neutrino" result was probably in 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.”

The epistemic consequences of bibliometrics-based evaluation

Until a few years ago, most Italian scientists had hardly heard of things like the impact factor of a journal or the h-index of a researcher; nowadays these seem to be their everyday concern. What are they about? They are some of the parameters introduced with the aim of quantitatively assessing the outcome of scientific research, giving rise to a new discipline called scientometrics, and in particular bibliometrics for what concerns the scientific publications.
