Abstract

We present Feynman- and Bjorken-variable distributions for the diffraction dissociation (dd) π^±p→π^±(πN)_dd at 6 and 16 GeV/c.
The Bjorken variable ⟨X_B⟩ averaged over a certain (πN) mass interval slowly decreases as the (πN) mass increases. The magnitude of ⟨X_B⟩ is considerably small, namely ⟨X_B⟩∼0.1 at M(πN)=1.5 GeV as compared with the value obtained in the lepton-hadron scattering. We found that the usual slope-mass correlation of dd was closely related with the mass dependence of the Bjorken variable.
