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 b...
