Abstract

The data on low--transverse-energy jets obtained by the UA1 Collaboration in CERN SPS Collider experiments at c.m.-system energy 200 to 900 GeV are analyzed. It is observed that the low-${E}_{T}$--jet events and the ordinary minimum-bias events are closely related to one another. Their relationship can be described by standard statistical methods. In particular, the existence of a narrow peak in the multiplicity distribution of low-${E}_{T}$--jet events is a statistical effect caused by the small \ensuremath{\eta}-\ensuremath{\varphi} window with ${E}_{T}$ cut used in the selection of such events.
