Introductionse of light quanta, the situation was exactly the reverse. The wave nature of light was a dogma of the nineteenth century. It was only with the discovery of the photoelectric effect that physicists were forced to think again. The revolutionary idea of Einstein—the hypothesis of light quanta, in whic

Linking Methods in Critical Point Theoryies of elementary particles. Examples are the electron (e), the photon (.), the proton (p), the neutron (n), the pi-mesons or pions (.), the K-mesons (K), and the hyperons (Λ, Σ, etc.). Of these, the electron and the proton have been known for the longest time. At the time when the electron was disc

Stephen J. Walsh,Kelley A. Crews-Meyeras it occurs when a beam of protons from an accelerator impinges on a target (Fig. 2.1.). If the energy of the incident protons is large enough, then as a result of Einstein’s equivalence relationship between mass and energy (Einstein 1905b), it is possible for the kinetic energy of the original pro

Richard C. Staples,Ronald J. Kuhre appropriate formalism for describing the quantum behavior of elementary particles is the . founded by Dirac, Jordan, Pauli, and Heisenberg (Dirac 1927; Jordan 1928; Heisenberg 1929,1930). An important feature of this theory is that it unites wave- and particle-like aspects. For example, quantum fi

The central role here is played by the scattering matrix ., which was introduced by Wheeler and Heisenberg (Wheeler 1937; Heisenberg 1943, 1944). Before presenting a general formulation we will look at a simple example.

The external field may be produced by some macroscopic device such as a capacitor or an electromagnet, but it could equally well be the field due to an atomic nucleus. Some typical problems of this nature are the following:

We know, however, that, in principle the theory includes higher order terms and that for a precise comparison with experiment, these too must be taken into account. After the development of QED at the end of the 1920s, it quickly became clear that in calculations of higher order terms, the

In this part of the book we will attempt to trace the historical path which led to QCD. Despite the existence of some impressive comparisons between experimental data and QCD, it should be stres
