The Mysterious Nucleus … why some nuclei are stable and others are not

Four Forces… Gravitation Electromagnetism Weak Nuclear Strong Nuclear Long range Short range

What is “stuff” made of? b (-1/3)‏ s (-1/3)‏ d(-1/3)‏ c(+2/3)‏ t(+2/3)‏ Hadrons can interact via all forces and are composed of quarks. Examples: baryons are 3-quark combinations, mesons are 2-quark combos (example: neutron is udd)‏ hadrons u(+2/3)‏ quarks Elementary particles – do not interact via strong force Come in 6 flavours. Leptons are: electron, electron- neutrino, muon, muon-neutrino, tau, tau-neutrino leptons
