Abstract The transverse momentum Bumpers balance of pairs of back-to-back b quark jets in PbPb and pp collisions recorded with the CMS detector at the LHC is reported.The center-of-mass energy in both collision systems is 5.02 TeV per nucleon pair.Compared to the pp collision baseline, b quark jets have a larger imbalance in the most central PbPb collisions, as expected from the jet quenching effect.The data are also compared to the corresponding measurement with inclusive dijets.

In C 500MG - PECH the most central collisions, the imbalance of b quark dijets is comparable to that of inclusive dijets.
