Abstract
According to the LPHD, the conversion of partons into hadrons occurs at a low virtuality scale, independent of the scale of the primary hard process, and involves only low-momentum transfer. The non-PT effects are reduced to a few normalizing constants relating hadronic characteristics to partonic ones. Various algorithmic model approaches to the quantitative realization of the LPHD have been discussed. There is, moreover, a consistent field-theoretic approach to the physics of colour blanching which exhibits LPHD properties, namely Gribov's confinement scenario. The authors focus on the conceptually simplest way to make an analytical model-independent prediction for the inclusive spectrum of hadrons. In the leading twist approximation, the spectrum is known to have a general factorized form in the moment representation.
