Limitations of Fermi Theory

Abstract

We noticed that there are no scattering processes of the form ν μ e-ν μ e-or ν̄ μ e-ν̄ μ e- in the framework of Fermi’s theory with V-A coupling. One therefore has to carefully investigate experimentally whether such scattering occurs in nature. These experiments are extremely difficult, because the expected cross sections (if any) lie in the range 10-41 - 10-44 cm2 (10-17 - 10-20 barn). Only with the high neutrino currents in modem accelerators (Fermilab near Chicago, CERN — SPS) and high neutrino energies (several hundred GeV) did such experiments become practical at all.

Biographical Notes

  1. SALAM, Abdus, theoretical physicist, *29.1.1926 in Jhang (Pakistan). He received his Ph.D. degree in 1952 from the University of Cambridge and became professor of Imperial College, London in 1957; since 1964 he is director of the International Center of Theoretical Physics at Trieste (Italy). His main work is on the two-component theory of the neutrino and on symmetry properties of elementary particles, for which he shared in the 1979 Nobel Prize in physics with Glashow and Weinberg.Google Scholar
  2. WEINBERG, Steven, theoretical physicist, *3.5.1933 in New York. He received his Ph.D. degree from Princeton in 1957, became professor at the University of California in Berkeley in 1960, later at the Massachusetts Institute of Technology, Harvard University, and since 1982 professor at the University of Texas in Austin. He made many contributions to the theory of elementary particles, including the unified electroweak theory, the theory of strong interactions, and to particle cosmology. He shared in the 1979 Nobel Prize in physics with Glashow and Salam.Google Scholar
