The measurement is performed using 1.72 nb-1 and 257 pb-1 of Pb+Pb and pp data, respectively. The large-radius jets are reconstructed with the anti-kt algorithm using a radius parameter of R=1.0, by reclustering anti-kt R=0.2 jets, and are measured over the transverse momentum (pT) kinematic range of 158<pT<1000 GeV and absolute pseudorapidity |y|<2.0. The large-radius jet constituents are further reclustered using the kt algorithm in order to obtain the splitting parameters, d12 and ΔR12, which characterize the transverse momentum scale and angular separation for the hardest splitting in the jet, respectively. The nuclear modification factor, RAA, obtained by comparing the Pb+Pb jet yields to those in pp collisions, is measured as a function of jet transverse momentum (pT) and d12 or ΔR12.
