We find that the positron and electron consist of the three fundamental particles, and , respectively. Furthermore, the members of the second and third generations quark composites consist of the first generation quark and the neutrino of fundamental particles. The particle and its anti- particle pair(or neutrino and its antineutrino pair) have to be an energy quantum (or a photon). The minimum Higgs boson (called ˇ°God particleˇ±) might be a neutral pion. The fundamental particles are simply up and down quark, neutrino, muon-neutrino, and those anti-particles. %K Members Of Electron And Positron %K Member Of Muon %K Members Of W< %K sup> %K +< %K /sup> %K /W< %K sup> %K -< %K /sup> %K //Z< %K sup> %K 0< %K /sup> %K /B And Higgs Boson %K Members Of Second And Third Generations Quark %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=5128
