The pi mesons + and - are each composed of two quarks. The quark composition

Question:

The pi mesons π⁺ and π^- are each composed of two quarks. The quark composition of the π⁺ is ud̅, while the composition of the π^- is u̅d. (a) What is the antiparticle of the π⁺? (b) The π^- can decay into a muon and an antimuon neutrino according to

π^- → μ^- + v̅_μ

What are the final quarks involved in this decay? (c) Does this decay conserve lepton number? If so, what is the final lepton number?
