Where Can I Find References on Composite Quarks and Leptons?

[francesco85]

Hello everybody; does anyone know a good reference (possibly modern) where one can study quarks and leptons (as well as gauge bosons) as composite objects? By reference I mean papers, books, reviews and every other thing you might find useful :)

Current theory says quarks and leptons are not composite.

I know that standard model assumes that all the particles described in it are fundamental; Aren't there extensions that assumes the compositeness of quarks and leptons? Why couldn't this explain the flavor puzzle for example? Isn't there any link with electroweak symmetry breaking? Why is it excluded? What about the Electroweak Precison Tests? Can you give a reference, please?

Here's a survey, although out of date. "Preons: Models of Leptons, Quarks and Gauge Bosons As Composite Objects", a book by I. D'Souza et al (1992).

To repeat Mathman's comment, this is a highly speculative topic unsupported by experiment.

Thank you very much for the reference.
For the sake of clarity, what do you mean by "unsupported"? Experimentally excluded? If so what experiments exclude the compositeness? Or simply experimentally not verified (yet)?
Thanks in advance,
Francesco

The TASI lectures by Chivukula http://arxiv.org/abs/hep-ph/0011264v1 would be someplace to start for some theory. Experimental search exclusions are summarized by PDG at

for vector composites and

http://pdglive.lbl.gov/Rsummary.brl?nodein=S054&exp=Y

for quark/lepton composites. You can click around there to find references to the original papers. Some recent publications by CMS are here:

Thank you very much, to everybody; I will have a look to the references you have given!
