Source sentences:
text: The discovery that neutrinos have a very small mass, at least a million times lighter than the electron, raises the possibility that neutrinos get their mass from unknown processes, that may not be related to the recently discovered Higgs boson.
text: However, the article about neutrinos says that this is not true, since neutrinos do have a small mass, even if all neutrinos actually observed were left-handed.
text: Since leptons are their own constituents, not made up of quarks or gluons, that implies that there is only two ways a neutrino will interact: gravitationally and weakly (however neutrinos generally have such small mass, that gravitational effects are negligible).
text: —that neutrinos do in fact have some very small mass, probably less than 2 eV/c2.
text: The discovery that neutrinos have a very small mass, at least a million times lighter than the electron, raises the possibility that neutrinos get their mass from unknown processes, that may not be related to the recently discovered Higgs boson.
text: A neutrino is a subatomic particle that is very similar to an electron, but has no electrical charge and a very small mass, which might even be zero.
