Can it be a little lighter? The neutrino on the scale

The neutrino: Hardly any other particle provides physics with more exciting questions. Why is it so much lighter than its siblings in the particle zoo - and what exactly is its mass? Is it identical to its own antiparticle? Are there other neutrino species besides the known three? Accordingly, many experiments are trying to decipher the nature of this particle. My group is involved in the KATRIN experiment at the Karlsruhe Institute of Technology (KIT). There, about 150 researchers are trying to find out the mass of the neutrino.
