Oct 14, 2019: KATRIN’S FIRST RESULTS AND A TACHYON MODEL
The first results from the KATRIN experiment can be shown to be consistent with both the existence of a single effective mass neutrino of mass under 1.1 eV, and also an exotic “3+3” neutrino model that had been proposed in 2013. This model assumes three active-sterile pairs, having specific masses, one of which is imaginary. This short paper shows how the experiment’s first results are consistent with the model. At the end of a year of data-taking KATRIN should have more than enough data to either confirm or disprove the model definitively. Faster-than-light neutrinos still live!
