Elementary Particles of Modern Physics
Robert E. Marshak · Science · 1960
An extensive discussion of elementary particles is presented and a total of 30 particles and antiparticles is given, 7 of which are genuinely stable. The following properties are tabulated for all 30 particles: spin, mass, charge, baryon number, lepton number, strangeness number, mean life, and decay modes. Particles differing only slightly in mass may be attributed to different charge states of the same particle. Each of the properties is studied in detail, and the reasons for the construction of the strangeness number are given. The three types of forces are discussed: strong (nuclear), electromagnetic, and weak. Finally, conservation of parity, charge conjunction, and time reversal are considered. (D. L.C.)
