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.
