摘要：

According to the cone definition of the jet we propose a practical and effective algorithm to identify jets. Through comparison between the Monte Carlo samples with and without jet(s), the following observations are made. Contrary to what is expected, most of the jetty events do not have high multiplicity. The distributions of multiplicity and (p) over bar t have long tails for the whole event sample because of (mini)jet production, but no such tail for a no-jet event subsample. The average transverse momentum per event (p) over bar t and multiplicity n are positively correlated for the whole event sample, and negatively correlated for the jetty event subsample. Two ratios are introduced to describe the "degree of hardness" of each event and are found to be correlated positively with (p) over bar t, but negatively with multiplicity, indicating that (p) over bar t is a better characteristic parameter to describe the event hardness than multiplicity.
