Abstract
The transverse momentum 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 5.02TeV 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 e ect. The data are also compared
to the corresponding measurement with inclusive dijets. In the most central collisions, the
imbalance of b quark dijets is comparable to that of inclusive dijets.
