Search for mirror neutrinos in the tritium beta spectrum
Description
Electron-like mirror neutrinos Nsub(e), if they exist, will be produced in tritium #betta# decay if they are kinematically allowed, and if the vsub(e)-Nsub(e) mixing angle does not vanish. Reactor antineutrino oscillation experiments limit the mixing angle to 12.30 (90% C.L.) which implies a fraction of at most 4.7% mirror neutrinos in tritium decay. A reanalysis of the Moscow tritium #betta# spectrum with such a fraction of massive mirror neutrinos allows the #betta#sub(e) mass to be lowered by 10 ev (at 90% C.L.), the Nsub(e) mass being > or approximately 80 eV.
