New measurement by OPERA…same strange result?!?!

So the BBC is reporting that the results of the neutrino run done most recently by the OPERA experiment is confirming their previous result and continuing to find superluminal neutrino speeds.

http://www.bbc.co.uk/news/science-environment-15791236

In this iteration of the experiment OPERA attempted to address, amongst many points, one of their largest sources of uncertainty. Namely, the bunch length of the protons that were being sent from CERN and were producing the neutrinos that they were measuring.

By shortening the bunch widths you have a greater certainty about where the neutrinos are being created and thus you know your initial time to a much higher degree of accuracy.

Needless to say this is a big deal if it is true.

They have updated their paper to include this systematic “fix” as well as complete discussion of various other effects taken into account can be found here on the arxiv.

This is a very exciting find in physics and with the reported plan to submit this paper for review to a journal a final vetting is in due course.

Now we must wait for this experiment to be repeated by the many other long baseline experiments, such as MINOS here at Fermilab and T2K in Japan!
