Work Step by Step

As discussed on page 930, neutrinos are leptons, and interact only via the weak nuclear force. If a neutrino (or an antineutrino) is among the decay products, the decay occurred via the weak interaction. Using this criterion, and looking at Table 32–2, we identify these particles from top to bottom: W, muon, tau, $\pi^+$, $K^+$, $K_L^0$, and the neutron, as well as their antiparticles. Furthermore, we see from the second column in the table that the Z particle and the Higgs boson also can decay via the weak interaction.
