Fermilab Double-Checking CERN’s (and their own) Math

Of course the big news of the past week is the OPERA experiment’s measurement of neutrino’s travelling faster than light.

The paper is up on arXiv. I’ve gone through it and nothing jumps out as to what they could have possibly done wrong. Chad Orzel on his blog Uncertain Principles has written a really nice summary of the paper and what the group actually did.

(Aside: I just read How to Teach Physics To Your Dog by Orzel, and I would definitely recommend it to a reader with a budding interest in quantum mechanics.)

Now it looks like the US based Fermilab is going to go over some old data to see if they can support (or contradict) the results of the OPERA experiment.

It was back in 2007 that Fermilab announced the results of their MINOS (Main Injector Neutrino Oscillation Search) experiment. They also found neutrinos travelling faster than the speed of light, however they had a much larger margin of error than the OPERA experiment, so they did not receive much attention.

Now, they are going to go back over their old data, as well as add some new data, to see what they find.

“The MINOS experiment has plans to update their original 2007 measurement with a number of improvements, including 10x more data,” wrote MINOS spokesperson Jenny Thomas, a professor of particle physics at University College London in an email to TPM’s Idea Lab.

“We should have a result in 4-6 months as the data is already taken. We just have to measure some of our delays more carefully,” she added. [TPM]

So in 6 months (I know, science is slow!) we will hopefully add another chapter to this fascinating story.
