  • Compositeness of Quarks and Leptons
    COMPOSITENESS OF QUARKS AND LEPTONS Michael E. Peskin Laboratory of Nuclear Studies Cornell University Ithaca, New York, U.S.A. Introduction The theoretical talks we have heard so far at this symposium have been full of precision and technical detail in explaining the consequences of the gauge theories of the strong, weak, and electromagnetic interactions. The level of confusion and far-reaching speculation has been remarkably less than at previous conferences in this series, in great part because our current theories seem to be both fundamental and in good accord with experimental data. One might wish to believe that the study of fundamental physics is almost complete. Is it true, at least, that the quarks, leptons, and gauge bosons that we now observe are among the most basic building-blocks of Nature? Despite the temptation to agree, a stream of theoretical papers - a stream which has, in the past year, become a torrent - has argued that they are not. I have been as~ed to review this set of theoretical ideas. My review will necessarily ;~ contain more than its proper share of speculation and guesswork. But I hope to ',' make clear both the current status and the consequences of the idea that the quarks and leptons are composite, that another level of fundamental physics lies waiting to be discovered. There is, at the moment, no experimental evidence which would require the compositeness of quarks and leptons. Indeed, the simplicity of their gauge interactions makes quarks and leptons look convincingly elementary. What, then, encourages physicists to take the notion of their cornpositeness seriously? Three reasons come to mind.

  • On the Concepts of Vacuum and Mass and the Search for Higgs
    On the concepts of vacuum and mass and the search for higgs L. B. Okun ITEP, Moscow, Russia September 10, 2018 Abstract Some recollections on the recent history of the concepts of vacuum and mass and the search for higgs. According to the widely spread terminology the Higgs field permeates vacuum and serves as the origin of masses of all fundamental particles including the Higgs Boson the higgs. Introduction This is a brief comment on the discovery of “a boson similar to Higgs Boson”, written on the request of Professor Phua and based on personal recollections and on my recent book “ABC of Physics: a very brief guide”. According to to the language of Feynman graphs accepted in this book the role of field is played by virtual particle. Madison 1980 – Bonn 1981 I am starting my comment with two conferences about 30 years ago in Madison and Bonn. In 1980 I was invited to give the summary talk at the 20th International Conference on High Energy Physics in Madison. I prepared the talk, but unfortunately was unable to participate in the conference as I was excluded from the final list of Soviet delegates. The extended text of the talk was published in May 1981 in the Uspekhi [1]. In the section 7 “Scalars” of this article I wrote: The experimental search for scalar particles is a primary task... What seems very promising is the associated production of Z and H bosons: e+e− → Z0H0. The search for this reaction is one of the most important tasks of the accelerator LEP.
