Abstract

Although the first results of the KATRIN neutrino mass experiment are consistent with a new
improved upper limit of 1.1 eV for the effective mass of the electron neutrino, surprisingly they are
also consistent with an exotic model of the neutrino masses put forward in 2013 that includes one
tachyonic mass state doublet having m2 ∼ -0.2 keV2 . A definnitive conclusion on the validity of the
model should be possible after less than one year of KATRIN data-taking.
