Mar 20, 2023 at 17:51 comment added N A McMahon The LHC-faster than light neutrino paper was actually the reason I said experimental papers should be given more leyway than theory papers. If reality violates our theories, no matter how nice/beautiful our theories are, then we need new theories. Though if an experiment says I timed a pulse of light reflecting off the moon with a stopwatch and got the speed of light is 6*10^8 m/s then the experiment is probably wrong.
Mar 20, 2023 at 10:07 comment added mlk I think the LHC-faster than light-neutrino paper ( link.springer.com/article/10.1007/JHEP10(2012)093 ) is a good example on how to do it properly. They had a result that broke relativity and they focused the whole thing on ruling out mistakes in the measurements. (Or at least, all mistakes except for a loose cable)
