Lesson plan
Bootstrap model
In particle physics, the bootstrap model, bootstrap principle or hadron boostrap is a superseded hypothesis about the composition of elementary particles interacting under the strong nuclear interaction. It uses general consistency criteria to determine the form of a quantum field theory from assumptions on the spectrum of particles. It is a form of S-matrix theory. The term is derived from bootstrapping as in 'pulling oneself up by one's bootstraps,' as particles appears from self-consistency. It was first proposed in 1959 by Geoffrey Chew to explain particles interacting through the strong interaction. It fell out of favor in the 1970s with the rise of quantum chromodynamics, which described hadrons (mesons and baryons) in terms of elementary particles called quarks and gluons. Nevertheless, the bootstrap model was important for the development of string theory.
