Deuteron color degrees of freedom and deuteron break-up at high energy

Deuteron break-up reactions are analysed from a QCD-motivated point of view. Production of a nucleon with hard momentum is considered as a result of high gluon exchange between three quark clusters in hidden-color component of deuteron wave function. It is shown that the model reproduces well the nucleon momentum distribution extracted from (d,p)-reaction at high energy as well as the tensor analysing powers T20 of this reaction and of the reaction of elastic pd-backward scattering. 19 refs.; 2 figs.; 1 tab.
