Alert WEIT reader Occam refers to the announcement yesterday from the ICARUS team working at CERN that if those pesky OPERA neutrinos had indeed gone faster than light, then they should have shown a loss of energy. They didn’t, so they didn’t. You can read two rather more worked out arguments, one experimental (here) and another that is theoretical (here).
What’s interesting is that Occam points out that our very own Torbjorn Larsson pointed this out in a discussion on WEIT: “-There is no Cherenkov radiation as expected for particles traveling faster than surrounding photons travel.”
As Occam points out, this is precisely the point made by Cohen & Glashow theoretically, and confirmed by M. Antonello et al. experimentally.
WEIT: it’s all you need!
