The neutrino and the weak force Spectrum of energy for emitted electrons Most electrons energy ‘missing’ Not accompanied by a photon Energy not conserved? Ang momentum not conserved? e.g. 1H3 2He3 + e → or no p+ + e- particle missing Wolfgang Pauli (1931): Chargeless (charge conservation) Massless or very small mass (some B particles of large energy) Theory of the weak force 3. Enrico Fermi (1934): In addition to strong force
