Hybrid Hadrons: Origins and Development
Abstract
Hybrid hadrons are states in which the gluonic field of the strong force contributes to the structure of the hadron. The idea arose in several places at nearly the same time in the mid-1970s because the advent of quantum chromodynamics made it clear that the carriers of the strong force are dynamical degrees of freedom. This resulted in the cavity resonators of the MIT bag model, in the vibrating strings inherited from the dual resonance model, in the Budapest membrane bag, and in a constituent-gluon potential model. The idea was subsequently developed in the early 1980s into a phenomenology capable of predicting masses, quantum numbers, and decay signatures. This article traces that history from the primary literature, giving close attention to dates of submission and to who first proposed what, and supplements the written record with recollections of many of the principal participants. It closes by surveying the current state of experimental, theoretical, and lattice research.
