Abstract:
We performed a search for any sign of an additional neutrino mass state in
$\beta$-electron spectrum based on data reanalysis of direct electron antineutrino mass
measurements in Tritium beta-decay in the Troitsk nu-mass experiment. The existing data
set allows us to search for such a state in the mass range up to $100$ eV. The lowest
value at a $95\%$ C.L. upper limit for the contribution of a heavy eigenstate into electron
neutrino is around or less than $1\%$ for masses above $20$ eV.
