ALICE measurement of h+jet acoplanarity in 0-10\% \PbPb collisions at \sqrtsNN = 2.76 TeV  compared to an embedded PYTHIA+\PbPb reference and JETSCAPE calculations, in pp and \PbPb collisions for charged-particle recoil jets with $R=0.4$ and $40\pTjet60$ \gev. See text for discussion of JETSCAPE calculations.
