Revisit to minijets in p(p)over-bar collisions at √s=630GeV

According to jet definition-cone algorithm to identify jets, we reanalyse UA1 minimum-bias non-single diffractive p (p) over bar data at root s = 630 GeV, The correlations between (p) over bar(t) and multiplicity for the event sample and subsamples are studied in detail. We found that they ai-e positively correlated for the event sample, while negatively correlated for the jet event subsample. The correlations and decorrelations between mini-jets are also studied. We further analyse the possibility of large rapidity gap existence between the two minijets, and find that there are no particles between two minijets in some events, but the statistics are not enough.
