Charged _ mesons, muons and antineutrinos, antimuons, neutrinos 1 of 13 What do _ mesons decay into when charged and not charged? If charged - decay into neutrinos and antimuons or muons and antineutrinos If no charge - decay into high energy photons 2 of 13 What do muons decay into? decay into electrons and antineutrinos or positrons and antineutrinos 3 of 13 What classifies as hadrons? baryons and mesons 4 of 13 What interactions take place for hadrons? intefere with strong interaction, most decay in week interaction 5 of 13 What do leptons interfere with? dont interfere with strong, only with the week interaction 6 of 13 What are the 2 branches of leptons? electron branch and muon branch 7 of 13 What do mesons consist of? quark antiquark pair 8 of 13 When is and isnt strangeness conserved? conserved in strong interaction, not conserved in week interaction 9 of 13 What type of meson has a strange particle? a kaon meson 10 of 13 What is beta minus decay, what is the exchange particle used? _ neutron rich nucleus, neutron-proton, Down quark to up quark, products are electron and antineutrino, exchange particle=w- boson 11 of 13 What is beta plus decay? _ proton rich nucleus, proton-neutron, up quark to down quark, productos are positron and neutrino. exchange particle=W+ boson 12 of 13 What is always conserved in decay? charge, energy, lepton number, baryon number 13 of 13
