SUMMARY

The Bootstrap Model, originally proposed by Geoffrey Chew, is no longer considered a viable theory for strong interactions, with Quantum Chromodynamics (QCD) being the accepted framework. John Schwarz highlights that while the bootstrap model has limitations, particularly in explaining certain particles like psi, its concepts have influenced modern string theory. The S-matrix approach within the bootstrap retains some useful aspects, demonstrating its historical significance in the development of QCD and string theories by Chew's students, including Schwartz and Gross.

PREREQUISITES
  • Understanding of Quantum Chromodynamics (QCD)
  • Familiarity with string theory concepts
  • Knowledge of the S-matrix formalism
  • Awareness of particle physics and known particles
NEXT STEPS
  • Research the implications of Quantum Chromodynamics (QCD) in particle physics
  • Explore the role of the S-matrix in modern theoretical frameworks
  • Study the development and principles of string theory
  • Investigate the historical context and evolution of the bootstrap model
USEFUL FOR

Particle physicists, theoretical physicists, and researchers interested in the historical development of particle interaction theories and their modern applications.

What are some of the problems with Chew's bootstrap model? Is it still a theory to be recognized and seriously considered?

Although QCD, not bootstrap, is the correct theory of strong interactions, according to John Schwarz, ideas behind the bootstrap have found their way into string theory. http://arxiv.org/abs/hep-th/0007118
 
The problem with the bootstrap is that there are known particles that can't be explained by the bootstrap (the psi discovery particularly), but quarks seem to work. The S-matrix part of the bootstrap still has useful aspects. Chew students (Schwartz and Gross) were part of the early development of QCD and String Theories, some of which were outgrowths of bootstrap S-matrix and Regge stuff.
