This book was released on 1994 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Matters are made of quarks and leptons. There are three families of them, each containing two quarks and two leptons. Ordinary matters are made of leptons and quarks of Family I. Quarks also come in three colours. The interaction of lepton and quarks are described by the Standard Theory, which is described by the gauge group SU(3) x SU(2) x U(1). It consists of the electromagnetic interaction mediated by the photon, the charged weak interaction mediated by the W+ bosons, the neutral weak interaction mediated by the Z boson and the strong interaction mediated byt he eight gluons.The charged weak interaction mixes quarks from different families. It is this mixing that gives rise to CP violation phenomena. [Author's abstract].
