The Z particles also decay into certain particles that then decay into the particles whose tracks are seen here. What are the secondary particles and the final ones?
3.
Answer:
One example:
Z -> a tau+ and tau-.
Then the tau+ -> a muon+ and neutrinos,
and the tau- -> an electron and neutrinos,
or with opposite signs
4.
Answer:
Similarly, Z -> a tau+ and a tau-.
Then the tau+ -> a muon+ and neutrinos,
and the tau- -> hadrons and neutrinos,
or with opposite signs.
