Abstract (data abstract)
CERN-LHC. The forward-forward and forward-central dijet azimuthal angular correlations and conditional yields are measured in Pb+Pb and pp collisions with the ATLAS detector at the LHC. The measurement is performed as a function of jets transverse momentum and rapidity. The analysis utilises an integrated luminosity of 25 pb^{-1} of pp data and 360 ub^{-1} of Pb+Pb data collected in 2015 and 2016, respectively, at the same centre-of-mass energy of 5.02 TeV per colliding nucleon pair. The measurement is performed in the center-of-mass frame of the nucleon-nucleon system in the rapidity range between -4.0 and 4.0 using the two highest transverse momentum jets in each event, with the highest transverse momentum jet restricted to the forward rapidity range. No significant broadening of azimuthal angular correlations is observed for forward-forward or forward-central dijets in p+Pb compared to p+p collisions. For forward-forward jet pairs in the proton-going direction, the ratio of conditional yields in p+Pb collisions to those in pp collisions is suppressed by approximately 20%, with no significant dependence on the transverse momentum of the dijet system. No modification of conditional yields is observed for forward-central dijets.
