Unformatted text preview: two electrons and an anti-electron. Hint: Check that the charge, lepton number, and baryon number are conserved A) Yes B) No Question 4: What does the following diagram show? A). Electrons interacting by the weak force B). Electrons and quarks interacting by the strong force C). An electron and anti-electron annihilating, leading to the creation of a quark and anti-quark. D). An electromagnetic interaction of electrons and quarks E). A gluon creating a photon and anti-photon. Extra Credit: A Positive Pion (charge +e) is a particle made up of a up and an anti-down quark. Pions decay by the weak force, that is the two quarks can interact by the weak force. Is the follow diagram a possible representation of that process? A). YES B) NO Check that the charge, lepton number, and baryon number are the same before and after...
