Minijet Production at Small x
  Soft pomeron exchange at high energy includes minijet production at central rapidity values. This predicts copious production of minijets in deep inelastic scattering at small $x$, which is closely related to the fact that $\nu W_2$ exhibits Regge behaviour. It helps to explain also how the integrated inclusive cross-section for minijet production in $\gamma p$ or $pp$ collisions can be much greater than the total cross-section.
