Frau Hagner, you are leader of the German group of the OPERA experiment. But one searches in vain for your name on the preprint.
I and a dozen of colleagues did not sign the preprint. I have no reservations about the experiment. I just think it was premature to go public with the results for such an unusual effect like faster than light travel. One should have done more tests. But then the publication would have taken at least 2 months longer. I and other colleagues from the OPERA collaboration wanted these tests to be done.
First, a second independent analysis. In particle physics, if one believes to have discovered a new particle or effect, then in general there is not only one group analyzing the data but several. And if all get the same result then one can be convinced it is right. That has not been the case with OPERA.
Because there hasn't been time. For an effect like faster than light travel the analysis should certainly be controlled. Maybe there is a bug in the program [...] The majority of the collaboration preferred a quick publication.
Hagner also says that the statistical analysis (matching the proton spectrum with that of the neutrinos) should have been redone by different techniques and that this is currently under way. She further points out that the results are only from one of two detection methods that OPERA has, the scintillation-tracker. Another detector, the spectrometer, should yield an independent measurement that could be compared to the first, but that would take about 2 months.
The final question is also worth quoting:
[If true], might satellite navitation in the future be based on neutrino rays rather than light?
Yes, maybe. But then our GPS devices would weigh some thousand tons.
