Revisit to Minijets in pp Collisions at s=630GeV

  • According to jet definition-cone algorithm to identify jets, we reanalyse UA1 minimum-bias non-single diffractive pp data at s=630GeV, The correlations between pt and multiplicity for the event sample and subsamples are studied in detail. We found that they are 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.

Abstract: According to jet definition-cone algorithm to identify jets, we reanalyse UA1 minimum-bias non-single diffractive pp data at s=630GeV, The correlations between pt and multiplicity for the event sample and subsamples are studied in detail. We found that they are 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.
