How to determine neutrino type [nuclear/particle phys]

  • #1
A beam of negative pions enters a bubble chamber and triggers the following reaction and successive decays all take place within the bubble chamber:

[tex]\pi[/tex]- + p [tex]\rightarrow[/tex] [tex]\Lambda[/tex]0 + K0

[tex]\Lambda[/tex]0 [tex]\rightarrow[/tex] [tex]\pi[/tex] + p
K0 [tex]\rightarrow[/tex] [tex]\pi[/tex]+ + [tex]\mu[/tex] + [tex]\bar{\nu}[/tex] [tex]\rightarrow[/tex] e- + [tex]\nu[/tex] + [tex]\bar{\nu}[/tex]

The question asks to determine the types on neutrinos in the K0 and [tex]\mu[/tex] decays, how do I do this? Do I assume, for example, that the electron neutrino always appears with the electron etc?

Try Lepton number conservation.
