Measurement of the production of neighbouring jets in lead-lead collisions at √sNN=2.76 TeV with the ATLAS detector

This Letter presents measurements of correlated production of nearby jets in Pb+Pb collisions at √sNN=2.76 TeV using the ATLAS detector at the Large Hadron Collider. The measurement was performed using 0.14 nb -1 of data recorded in 2011. The production of correlated jet pairs was quantified using t...

This Letter presents measurements of correlated production of nearby jets in Pb+Pb collisions at √sNN=2.76 TeV using the ATLAS detector at the Large Hadron Collider. The measurement was performed using 0.14 nb -1 of data recorded in 2011. The production of correlated jet pairs was quantified using the rate, R δR , of "neighbouring" jets that accompany "test" jets within a given range of angular distance, δR, in the pseudorapidity-azimuthal angle plane. The jets were measured in the ATLAS calorimeter and were reconstructed using the anti-k t algorithm with radius parameters d=0.2, 0.3, and 0.4. R δR was measured in different Pb+Pb collision centrality bins, characterized by the total transverse energy measured in the forward calorimeters. A centrality dependence of R δR is observed for all three jet radii with R δR found to be lower in central collisions than in peripheral collisions. The ratios formed by the R δR values in different centrality bins and the values in the 40-80% centrality bin are presented. © 2015.
